COVID-19-STAT | web application to keep track | Dataset library

I am consuming a Web API, but when serializing I get this error:

Cannot deserialize the current JSON object (e.g. {"name":"value"}) into type 'System.Collections.Generic.List`1[Covid.Models.RegionsModel]' because the type requires a JSON array (e.g. [1,2,3]) to deserialize correctly.
To fix this error either change the JSON to a JSON array (e.g. [1,2,3]) or change the deserialized type so that it is a normal .NET type (e.g. not a primitive type like integer, not a collection type like an array or List) that can be deserialized from a JSON object. JsonObjectAttribute can also be added to the type to force it to deserialize from a JSON object. Path 'data', line 1, position 8.

I read several possible solutions, in questions that have already been asked but could not get it to work.

JSON.NET DeserializeObject to List of Objects

Cannot deserialize the current JSON object (e.g. {"name":"value"})

If you could help me please, I have really tried for 3 days but I can't solve it.
