Shortcut sending not working with Microsoft Remote Desktop 10

Still experiencing this same issue.
I used to love BTT when I had my old mac. I spend much of my day working in Amazon Workspaces doing development for work. Therefore, I bought a new BTT license with the goal of creating many automations that would help my workflow.
However, I am experiencing the same issue as described above, namely that modifier keys are not passed through to the remote machine.
e.g.
two finger tip-tap-right mapped to Ctrl-C only passes in "C". This is the same issue with all modifier keys.
It seems that the same bug has been opened for many different remote desktop applications and use cases. See below:

  1. BTT and Microsoft Remote Desktop
  2. BTT not working with new Microsoft Remote Desktop
  3. Microsoft Remote Desktop 10 mouse button shortcuts not working
  4. .....................bettertouchtool-does-not-work-with-amazon-workspaces/1874/5

I am using BTT Version 3.504 on a MacBook Pro 16 inch on macOS Big Sur 11.1 and connect to a Linux Amazon Workspace. My modifier keys work in my linux workspace when pressed on the keyboard.

Squashing this bug or providing a workaround would be really appreciated.

Thank you!
