Where do you provide SSL keys when creating service

On the “Create New Services” page, I’m setting us a service and want to use SSL keys as part of the security model. I can see a place to provide the SSL mode (in my case, required) but there is no space to provide an SSL key.

I’ve two instances running - one connecting to a MySQL db and another to a PostgreSQL db - but do not see the input space for the certs.

Does anyone else have this issue? Or are only connections without certs available?

Thanks.
