Additional context
I see in Library\PackageCache\[email protected]\ that some files/folders have .meta files, but the ones mentioned in the error messages don't.

This repo has been neglected. It actually not compatible with UPM

I have forked and do all upgrading https://github.com/Thaina/play-games-plugin-for-unity/tree/master

You can compare the change here #3304

@Thaina Thank you. The package in OpenUPM links to this repo. Should it link to your fork?

[Thaina]

I don't know if my fork really compatible with OpenUPM, and also who and how to publish this package into openUPM in the first place. Maybe that person can verify if my package should be in OpenUPM or not

I see the name ltmx but I don't know should I contact that person

[Thaina]

Instead I would like to recommend you using git dependency instead of openUPM
