time-input | A keyboard friendly react component for capturing time

I am trying to have validation that prevents the user from typing invalid numbers for this time format m:ss (m = minute, s = seconds).

I.E) 1 minute and 30 seconds = 1:30, 1 minute and 59 seconds 1:59. This would not be allowed: 1:61 or 1:77, since those are not valid seconds.

The first s can only be values 0-5, the second s and m can be 0-9

In Vue I have this in the text input box

When the start button is clicked, it is supposed to start a timer that executes a function every so often until the stop button is clicked. After digging a little bit on the internet I found that SetInterval() function should do that. This is the code I have:
