The rule that runs cms.dialysis.search safely

cms.dialysis.search 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 Apibase, apply this rule, and every cms.dialysis.search call is checked against it from then on.
