2 locations and Google/Alexa integration

I am unable to use my Google Home Mini or Echo Dot in my second location to control anything. In the first location it shows Amazon Alexa cloud and Google cloud in the Other section of Installed SmartApps. I can’t figure out where or how to add those SmartApps to the other location.

The hub in the first location is a V2 and the hub in the second location is a V3, if that matters.

I have read one other thread specific to an Echo but got lost down the thread as the last update was from 2017. This does not seem like something that would be that uncommon for one person/family to have multiple homes and want to configure automation in both?
