WHY IT NEEDS A POLICY

Why appflowy_accept_invitation needs a policy

Accepting an invitation creates a new association (workspace membership) and modifies the invitations collection by marking one as accepted. This is a reversible write operation—the user could potentially leave the workspace or decline invitations in the future. It's not destructive (irreversible deletion), not financial, and not code execution.

From the tool's definition The tool 'accept a workspace invitation' performs a state change by converting an pending invitation into accepted membership, modifying the user's relationship to a workspace.
