How do I create a Power Automate custom connector via REST calls (like in Postman)?

Question

Does anyone know if Power Automate exposes API's to let me create custom connectors through REST calls instead of the UI? I've scoured the internet and so far I only see creating and updating flows via REST.

I can't try anything because I don't know what URL's to call and the JSON payload I need to send.

Turns out only the CLI (paconn) can perform this as of now. Hopefully in the future Microsoft will expose the API.
