Set default view for Nextcloud office documents

I like that I can set my docs and spreadsheets to dark mode, and change the menu from compact to tabbed, but I would like to apply these settings universally so all users will have the same settings. Is this possible?

Related: when my menu is in tabbed mode, I like to collapse it so I don’t see all the icons. However, when I re-open a file, the Home tab is open again. Is there any way to suppress this?

Many aspects of the Collabora suite can be managed through coolwsd.xml file (see Configuration — SDK https://sdk.collaboraonline.com/ documentation). for CODE specific questions I would recommend to ask Collabora forum
