I think they work if you install Google Play Services (as a sandboxed app). What doesn't work for me is contactless payments with Google Pay however Google Wallet itself works. But I think that is actually intended and for security reasons.

Google Wallet is usable on GrapheneOS, but Google artificially restricts contactless payment functionality to Google-certified OSes.

It's not a real security check that they're doing, but rather just checking for certification, which is very unfortunate.
