Find Old Clash Royale Account by Name


I am Searching for a clash royale Account that i created a few years back when i was little. Since that a few things changed and i dont know any emails or anything from that time.
I have the Name Tag of my account tho because a friend still had me in his Friend List.

Hosenklunker #9GPGPL2V

I hope this is enough to recover it !

Thank you in advance!
