How do I fix the account missing permission bug for Huawei p40 pro at lol wildrift?

As already described in the title, I would like to know if and how it is possible to play wildrift for Huawei smartphones without Google service.

I'm not a riot support, but write to them.

The game is in beta and still has a lot of problems.
