Can I whitelist second Google Worspace to schedule meeting on the Google Meet device that belongs to different Google Workspace?

I have two companies in one building - each company has it's own Google Workspace (Company 1 - Google Meet Hardware, Company2 - NO GOOGLE MEET).

We have one conference room in the building which has a Google Meet Hardware that is attached to Company1 Google Workspace. What I am trying to figure out how can users from Company2 schedule meetings on Company1's Google Meet Hardware.

My initial steps was to figure out what is the Google Meet hardware's email address and I would have Company2 users to add that email address as user to their meetings, but unfortunately Google Meet that belongs to Company1 is rejecting these meetings even if there is no conflict. I think this is all related to the fact that these two companies have each their own Google Workspaces. i was hoping that I can whitelist Company2 domain on Google Meet Device, but I did not find the place this can be done.

Any help would be greatly appreciated.
