EDIT: @imsnif Sorry to bother you; please disregard this message entirely. I found a better way to set the action permissions for each action individually directly in the associated .yml file.

@imsnif Would you be willing to add write contents permissions for the GitHub action added by this pull request?

I believe one way to do that is to allow all actions read/write access.

This could also be done with a finer level of control if you like by only allowing certain actions to have write contents access.

Done!
