Nest cam volume after migration to Home

[BoiGrrlWonder]

I have several types of Nest Cams. Nest Outdoor Security Cam Wired, several Nest Cam 3mp Indoor Security, I also have Nest Doorbell Wired and Google Nest Hub Max (still in the Nest App) that all seem to have also lost the volume slider. I only have Microphone on/off and Audio recording on/off.  In the nest app, I was always able to turn up the volume to hear what's going on in the room. I can't find that option on the Home App (Android) or the Web app. Trying to listen to what's going on or hear who is at the door is nearly impossible. My phone volume is turned up all the way and my computer is  blasting so loud my wife can hear when I get emails but I can barely hear the delivery guy at my door. Any help would be appreciated.

In the Google Nest app, if you click on the Microphone icon while viewing a camera, and then click or hover in the lower left corner of the camera view, a volume slider icon appears in the lower left corner.

On the home.nest.com website, if you hover your cursor over the camera view, a speaker icon appears in the lower right corner, and if you hover over that icon, a slider icon appears.

I don't see an equivalent in the Google Home app or on the home.google.com website.

(We migrated our Nest Account to a Google Account in 2020, but have NOT "transferred" any of our 1st gen cameras to the beta "Public Preview" version of the Google Home app.)
