Read again:
I got permission from Warxander.
Now read the forum rules again:
Sharing content that is not yours is allowed as long as you credit the original author and don’t violate their terms/license. Try to contact the author via their contact information found on their profile, leaving a comment/reply, or by creating an issue (if it’s a repository). After allowing the original author time to reply ( ~1 week ) and you’ve not received a reply, you may use their content under the terms that you credit them and share your contact attempt (i.e. with a screenshot).
Only thing I didn’t do is sharing my contact attempt (because a direct message is above anything private) but mentioned that I would provide proof on demand.
So yeah, I got the permissions I could get and am save according to the release rules. Also I specifically mention that I hope Brent will give his permission (read that as I will remove radialmenu if he voices that he doesn’t approve of it).
Is that enough permission for you?
