Permission for a semantic model behind another semantic model

Hello everyone,

I have a report that's shared within my organization. The report is based on the semantic model R (see picture).

Yesterday I added two more semantic models (S and G). They are fairly large and don't need as many updates as R so I decided not to include them in R.

Here is the problem. All tables that contain information from tables from S and G cannot be viewed by organization members. Only by me. How do I extend their permission?

Greetings from Germany
