[test] SmartThings QA on google Home?

Hello all,
Just one question i can’t found any answer,
In the google Home app, under “home control” an “+”
I have “[test] SmartThings QA
When i choose this, it redirect me to the signin smatthings
I choose my location and i can’t Authorize because of
“client is not associated with a smartapp in location”

Someone know what is “[test] SmartThings QA” and how i can active this?
There is a difference with the SmartThings / Samsung Connect google home app?

Thank you in advance
