Eg: check the settings / compatibility / on your iPhone:

Use hearing devices with iPhone – Apple Support

Above article also says:

"Stream audio to your hearing devices

You can stream audio from Phone, Siri, Apple Music, Apple Podcasts, Apple TV, and more. Tap  in Control Center, on the Lock Screen, or in the Now Playing controls for the app you’re listening to, then choose your hearing device".

You can also automatically route audio calls to a hearing device.

You might want to check your hearing aids are a compatible model:
