Watch8 + Pixel10 issues

[sats]

Hello 

I am trying to setup watch8 standalone t-mobile line from my pixel10, I am unable to see the "Setup the child line" . I have created a a google account / family link and added as a supervised memeber in the family for my son.

I am stuck with a watch8 and t-mobile line and unable to use it .. it always picks up my own gmail id whenever I connect to the google account 

What is the way out here ! pixel 10 is all updated with latest SW versions
