+OK, it's also awful to set this up. Do you see a pattern emerging? :)

+- fake that you have the required tokens:
+  - `abra app secret insert example.com signal_hs_token v1 foo`
+  - `abra app secret insert example.com signal_as_token v1 foo`
+- generate the database password:
+  - `abra app secret generate example.com -a`
+- deploy the thing and then check the `/data/registration.yaml`
+- rm the fake `signal_hs/as_token` values and re-insert the new ones from `registration.yaml`
+- re-deploy the whole thing and then it should come up, message `@signalbot:example.com` to test
