addtocalendar | Free customizable JavaScript widget Add to Calendar | Calendar library

I have a sheets-bound script at the moment that reads the spreadsheet data and creates calendar events based on the sheet. That spreadsheet also stores other user's calendarIDs (not owned by me) for which I am trying to read/write their google calendar's.

My ideal usage flow was that a single user could trigger the script for all stored users OR each user could click on the script and have their events added to their specified calendar but I found that I am unable to even access other's calendars with just their calendarIDs.

My code was crashing earlier after I created a test calendar on a different google account. I toggled the calendar to public and am now at least getting null as indicated by the getEvents() documentation. I then subscribed to that calendar and received "exception: Action not allowed".

I have come across OAuth2 and feel like this is something I need to somehow implement but I was not sure how to go about it. Am I able to make changes to multiple usere's calendars from the script or do I need to learn about webapps and would that allow me to somehow access other's calendars?

Edit: I'm not a domain user, just using private personal google accounts

Edit 2: Also found out add-ons are a thing. Going to read about that

I'm using objective-c. I'm quite new to this. I have tried dozens of different ways to accomplish this. I have searched for the answer on google and on this forum. I have been trying to solve this for several days now. I'm sorry for asking for help.

I am using a library that renders a certain button to my layout. This is the library react-add-to-calendar.

I don't have any customization options, so I am currently wrapping the button in a div that gives the button the look that I want. The problem is though, that the child component only takes a very small portion of the parent component, and only the child component reacts to the click. So for the user, there's a button, that most of it is unclickable, even though it looks like it should be. Only clicking on the text itself sparks the desired action.

How can I make the whole button react appropriately to the click?

This is my code:

I got crashed when i click Confirm button and this form my logcat:

I was struggling for a couple of weeks to get the react-native-calendar-events library working on my React Native project after it was upgraded from 0.53.3 to 0.60.4.

I was able to get it working on the iOS side via refactoring some code to execute authorizeEventStore before checking authorizationStatus like so:

I'm presenting a EKEventEditViewController view with some predefined information. If the user doesn't want to change this information, he should be able to tap Add to add the event to the calendar.

The problem is, the Add button is disabled by default. It is only enabled if the user changes something (like the event name or the Calendar, for example).

My react-native-calendar-events code is throwing an error, the error is saying No calendar has been set, but I don't know why this is happening. The same code on the legacy version of my app works on the same devices.

I search how to edit the date of my event in iOS calendar app. I have succeeded to add the event but the date is always the date of the day. I search how to programmatically a precise date (for example: May 10 2019 at 08:00 pm).

Here is the code I added to add the event in calendar.

My code is work fine in add new event to sql database .

but Not display the event stored in sql inside the calendar.

I WANT TO DISPLAY THE EVENT INSIDE THE CALENDAR
