How to update sentinel policies from vcs(one centralised repo) to all org and workspaces using tfe

Use case:

Using one repo in git, I need to attach the policy set in all organisations. I used tfe to create policy set to all org and workspaces. However I couldn’t attach vcs connection to the policy set in organisation via tfe. Example:

Org A (sentinel policy workspace )
Org B
Org C
Org D

I can create policy set from org A to other org(B,C,D). However i couldn’t attach vcs connection to the policy set in other org. I get “Oauth token doesn’t exist”. Can you help me how to achieve this?
