Multi users with only one Gmail account

[Bulubulu]

Could I create an application for an association with one and the same gmail account for all users, as if there was only one user? It would obviously be possible, but what concrete limitations would that imply?

The implications are high risk of security breach and violation of AppSheet's Terms of Service that you had agreed to in order use AppSheet.

Exactly this.

That organisation is also every day at risk of losing access to their account, as it is a breach of Google's Acceptable Use Policy to share credentials of any accounts.
