I am creating a project to be able to share a Calendar among some users.
The strange thing is that when one of the users wants to connect, the following error appears telling him "This app isn't verified"
I am not a programmer so it is difficult for me but I think I am doing everything right.
The only api that I am using is that of Google Calendar.
The email with which I am creating the Api is a @
gmail.com

I am not using any special scope that requires some type of verification.
I did not exceed any quota limit or anything like that.
And the send to verification button is disabled and tells me that my changes do not require verification
I want any user with a Gmail email to connect to the calendar
What i need to do??
For the doubts I have verified the domain thinking that it was that but it did not solve the problem either
