Why can't I change the security permissions of this game from the Xbox gamepass?

Thank you, but I have one more question, after that update comes (hopefully soon) every single one of our games will be able to be modified with as we please right? Not just the ones tagged with "available to mod" right now in the xbox store?

So, I asked around with my team and it looks like the permissions may only be able to be changed if you're an insider.

If you check out this video: https://www.youtube.com/watch?v=ea4-mxDSz6I

The mod support will come with the freedom to download and allow users to create and save game files anywhere, which in turn gives you the ability to modify permissions.

As a standard user, the permissions changing may be blocked as an overarching security feature to protect the integrity of the game files.

Yes I've tried that now, still the same error

I checked and was able to change the permissions of the games I had on steam (And the mod also worked on them), this is only an xbox thing it seems

I also browsed that thread but nothing helped me so far

No that feature isn't there
