Automatic totp copy doens't work with Chrome (Brave)

Hi, I am using the Bitwarden browser extension in Brave Browser on macOS but unfortunately the automatic totp copy feature doesn’t work.
It works just fine in Safari and Firefox but when using Brave it just doesn’t copy the totp-codes to the clipboard automatically. Until a few weeks ago it worked without any problems, but lately I always have to copy the codes manually. On Windows, by the way, the feature works fine in Brave.
I already checked if autofill on page load was enabled, but it wasn’t.
Does anybody know how to solve that issue?
