Mutual SSL Authentication

I have the meteor app A that should connect to a custom WebSocket in meteor app B.
Meteor app B has no access to DB, it’s very dumb and only exposes a WebSocket where users from meteor app A containers connect to broadcast some messages.

I could try to add some JWT auth between 2 apps but found out about Mutual SSL.

How can I accomplish Mutual SSL Authentication between 2 meteor apps?
