How to prevent user from other tenant/environment to open and edit an app in PowerApps Studio?

Hello! Here's my problem: I'm creating an app in PowerApps for a user (a client) not in my tenant/environment. The goal is to export the app I create and give it to said user preventing him from opening it in PowerApps Studio. The user should only be able to use the app with his data(connecting it with his data source) and sharing it within his environment, but he shouldn't be able to edit it in PowerApps Studio.

So is there a way to do that? To allow only few modification regardin data connection but prevent others like opening and modifying the app?

Thanks in advance
