Re: "hearing health is not showing up when i try to use the hearing aid function for my airpods pro 2 on my mac"
You will need to have the test results available, in order to follow the set-up steps in the article below.
See how to: Use the Hearing Aid feature on your AirPods Pro 2 - Apple Support
Eg: says:
"Set up and use the Hearing Aid feature
Hearing Aid uses the results from the Hearing Test that you took on your device or audiogram results from a hearing healthcare professional to customise the sound of your AirPods for your specific hearing needs. The Hearing Aid feature is intended for people 18 years and older with perceived mild to moderate hearing loss."

Re: " ... can anybody help me get the hearing aid function working?"
You will first need a test result showing "mild to moderate" hearing loss.
(ie: For "serious" hearing loss, seems best to consult with a hearing-professional.)
Although the video below is for setting up hearing health features on iPhone,
it may help to familiarize you with the similar "set-up" on Mac, now that the features can also be used on Mac.
