Showing a board I am guest in, in my Desktop interface

I have a account that I use with my internal Team. My client wants to create their own account for their internal team and add me as a guest to their board. When I open the guest invitation link it seems to send me to a whole other Monday account, I would love for this board to show up in my Main Worskspace so the tasks my client has with me show up under My Work tab.

What is the best way to handle sharable board among different clients? I need to be able to access these boards easily from my Desktop App.
