Scenario: Creating a team in Teams app where files are stored in various channels, i.e. in a SharePoint library. In addition a form in Forms is created and linked to this same Team. This form has mandatory fields. When creating this Form, new columns representing the mandatory fields are added to the document library and thus also become mandatory for the other existing files in the various channels (library). Hence, it would be useful to be able to have different columns (mandatory or not) for different channels in the Team.
