Help PLEASE – Can Google track RCS messages for a missing person?

Hi, my girlfriend is missing (Stratford, ON, Canada). I, her family and the police are looking for her. She had been missing for two hours now. I can see that she is reading her messages through RCS. She has a Pixel 6a. Is there any way to track her? I can put whoever can help in touch with the police. She is very suicidal and already attempted twice.

Please help. We are desperate to find her. Any advice welcome.
