How to access the phone contacts in beeware (all names and phone numbers and make calls)?

Question

I want to access the contacts, their names and phone numbers in my programs and use them in my program, and also how can I make a phone call with a number by pressing a button. I could not find this feature in beeware. Please guide me if possible, if not, how to use the java code to do this in beeware and connect to my program and exchange data with python. I will be grateful if you answer

From https://github.com/beeware/briefcase-android-gradle-template/issues/65:

You can access any native system API using the Chaquopy bridging layer. Wrap any class you need with a jclass object (or get one implicitly via import), then invoke the native system APIs from Python as if they were Python methods.
