Show reason why group restriction not possible for that app

Papercut from #2672

cc @eppfel @MariusBluem because you always asked for this

[wiswedel]

@MorrisJobke Is this still of interest or can it be closed? Can't there be several reasons - none of them giving the reader any practical benefit?

Can't there be several reasons - none of them giving the reader any practical benefit?

Yes there can be different and it would be helpful to communicate why given features are not there IMO.

I suppose these are the reasons:

server/apps/settings/src/mixins/AppManagement.js

Lines 74 to 82 in 7ddad46

	canLimitToGroups(app) {
	if ((app.types && app.types.includes('filesystem'))
	|| app.types.includes('prelogin')

	|| app.types.includes('logging')
	|| app.types.includes('prevent_group_restriction')) {
	return false
	}
	return true

	];

Apps this applies to:

For many (most?) of these it's somewhat obvious why they can't be limited. But I can see how a few might be surprising (e.g. Collectives, Photos, Maps, Community Document Server, Office Online, Activity).
