Perhaps there may be an update to the iOS 15.(5?) which may help
whatever iPhone version you've there, with Accessibility features?

• iPhone User Guide (Table of Contents) - Apple Support

Features covered under 'Accessibility' could be likely place to start.
While I've gotten almost nowhere with Siri, might be useful(?) And
iPhone user guide Table of Contents @ first item, helps find stuff.
Sorry to not be of much help.
You may also be able to reach someone at Apple by phone, or chat.
In upper right side, 'Get Support' opens into a portal that eventually
can get you a real person. Good luck..!
