Jami on Android 10

Hello, I have Jami on my Android 10 phone.
I configured a SIP account and it works.
How do I get my contacts to show up in Jami?
Also, if I try to make a call from Contacts, I want the phone to ask me which app to use, either the default dialer or Jami. How do I get Jami registered as an app that can make phone calls?

I granted it all the available permissions.
