Hi! I've modified the PR in order to fix merge conflicts, and I've noticed that a couple of checks are failing.

First IIUC, checks if the fork is synced (it is), so don't know what's expected there. As for the second, it complains about a lot of files with missing / incorrect license headers, unrelated to the PR.

Is anything else needed in order to get the PR merged?

thx in advance
