I manage a band goes by the name ThirdLead. They have a single currently Live on Deezer (Lost Forever). I tried to claim the artist profile but on searching for it, it does not exist.

https://deezer.page.link/MJoNuTSKtLk3LgbW6 is the link to the artist song on deezer.

Kindly help me rectify. 

Much appreciated
