cant connect deezer wear os from Iphone

Hi, I just bought a montblanc watch working on wear os, which is up to date, as well as my phone (iPhone 13), and can’t link my account (part of a Deezer family) to the watch. The only option proposed is « log in with phone » and when I click it I only get the message « hold your phone close to your watch to log in », and cancel or retry as only options. I’ve tried to delete and reinstall app, restarting both devices, installing deezer for the watch from the google play on my iPhone, but still nothing. Could you get me a solution for me to be able to use deezer on my watch ?
