How to connect My 3dsmax work in a live Edit from My collaborator Create USD File?

Hi Everyone !
I’m Pretty New to the Omniverse Workflow, And we managed with a friend of mine to collaborate on the same usd file into Create.
Actually he created the session and I can work with him on it using Join session, and the problem is that I wanted to try to link This file with MY 3dsmax work on live edit Mode.

Here is the issue,
I try to Open The Content USD File from Max, However there is Only MY Nucleus account that shows up…
But the file we are Working on is on HIS Nucleus account…
Could you help us to find the solution or a certain workflow to resolve this problems ?

Thank you for your time ( And sorry for my english, It is not my maternal language ;) . )
