The rule that runs openfigi_mapping safely

openfigi_mapping is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every openfigi_mapping call is checked against it from then on.
