Post-Hoc Games-Howell Test

I'm currently analyzing more than three groups, but since the variance of the groups is not the same, I'm going to perform games-howell as a post-test method.
This post-test was previously included in the "userfriendly science" package as an option called posthocTGH, but this option disappeared when the package was changed to ufs.
I can't find a way to do this test right now, so I was wondering if there's a way to do this post-test.

what about:
r rstatix::games_howell_test() ?
