Phone assistant launches Bixby instead of Google assistant

I have a Galaxy S23 Ultra.  I just got my new Fenix 8 and when I launch "Phone Assistant" my phone brings up Bixby instead of Google Assistant.

How to correct this?

I have gone into Settings -> Advanced -> Bixby  and performed "leave bixby", then I restarted the phone.

No dice.

Help?  :-)
