How can I get the location information on the Arduino Portenta H7?

Hi guys.
I am testing my Portenta H7 to use its BLE 5.1 capabilities for indoor location, so far I have not been able to find documentation that allows me to obtain the necessary information for this, that is, the distance and departure angle between my Portenta and a smartphone connected to him. Could someone in this forum guide me on how to get this information? I have reviewed the ArduinoBLE library and I think that no options have been added for this yet. Is there any other library that I should include?

Thanks a lot
