This flag has been in Edge canary for some time but it started working since today's update, Edge Version 89.0.711.0 (Official build) canary (64-bit)
you need to enable this flag:
restart browser and when you right-click on a tab, you will have that option to move tab to a different profile window. of course first you have to have at least a 2nd profile in Edge for this to work.
p.s the other profile doesn't need to be open or running.
I'm hoping in future we will be able to use drag and drop to move tabs between 2 open Edge profile windows.
