Jump.chat with self-hosted nonfederated Matrix

Hi,

I run a private, non-federated Matrix server (synapse) that I use as a way to combine my messaging services into one app (Element). I'm currently using Google Voice with the Mautrix-gvoice bridge, but I am fully de-Googling.

What would be the process for connecting multiple JMP.chat numbers in via a bridge? I assume by using the XMPP bridge in some way.

I plan to still use the Cheogram app for calling.

Thanks.
