Configurable tab not showing on mobile

Hi,

We're creating a custom app in Teams. We have a configurable tab that isn't showing on mobile device except when we put the "team" scope in the manifest for the "configurableTabs". Except our application isn't meant to be used on teams but only in meetings.

If we don't have the "team" scope and only the "groupchat" as it is what the app is based for, the application is showing in the meeting but when we click on it Teams shows us an error that say this:

Anybody got an idea on how can we fix this error? The "team" scope ain't a problem for us but it seems to be a problem for the Microsoft App submissions.

Thanks for your help
