We successfully set up a SPO organisation asset library according to this documentation:
Create an organization assets library - SharePoint in Microsoft 365 | Microsoft Docs
Templates are not showing in "New" menu of our O365 desktop apps (E3 licence present).
In Word they are visible at the start page in a "recommended for you" section so it seems to work partially.
Before we distributed templates using a fileshare and GPO to set workgroup templates.
Could that be a reason?
SOLVED: GPO "Hide file locations when opening or saving files" was in place
