Trigger function in postgressql not working, after INSERT,UPDATE,DELETE operations

CREATE OR REPLACE FUNCTION notify_tenant_work_order_status_cud() RETURNS TRIGGER AS $$
DECLARE
row RECORD;
output JSONB;
row_obj JSONB;
payload JSONB;
final_payload JSONB;

BEGIN
-- Checking the Operation Type
IF (TG_OP = 'DELETE') THEN
  row = OLD;
ELSE
  row = NEW;
END IF;

-- Forming the Output as notification. You can choose you own notification.
output = jsonb_build_object('operation', TG_OP);
row_obj = jsonb_build_object('row', to_jsonb(row));
payload = output || row_obj;
final_payload = jsonb_build_object('id', jsonb_extract_path_text(payload, 'row', 'id'), 'operation', jsonb_extract_path_text(payload, 'operation'));

-- Calling the pg_notify for my_table_update event with output as final_payload

PERFORM pg_notify('tenant_work_order_status_cud'::text, final_payload::text);

-- Returning null because it is an after trigger.
RETURN NULL;
END;
$$ LANGUAGE plpgsql;

CREATE TRIGGER trigger_tenant_work_order_status_cud AFTER INSERT OR UPDATE OR DELETE ON tenant_work_order_status FOR EACH ROW EXECUTE PROCEDURE notify_tenant_work_order_status_cud();

when any Insert,Update and Delete operations are perform on the tenant_work_order_status table it should notify on the tenant_work_order_status_cud() channel. It is not working as expected.

We have same triggers on other table, where it works fine.

Any possible help would be appreciated.
