Omnibus fc with px4flow flow sensor

Hi, i am new to ardupilot etc. but i am working on a project and i need some help with it.

The goal is to have people who are new to flying drones perform some tasks indoor with quad. It would be the best if the drone could somehow have a position hold function. A friend of mine mentioned that a flow sensor would be a good option.

How do i know that the sensor and fc board i want to use are compatible?
For the fc i was looking to use the Airbot Omnibus F4 V6 and for the flowsensor the px4flow.

thanks in advance.
Kind regards,
