Unfortunately, that's true. With the older Nest cameras, we could go into the Google Nest app and change Wi-Fi settings. With newer devices and in the Google Home app you can't.
Now, Google Nest recommends that when you get a new router/modem, you give it the same network name (SSID) and password as on your old router/modem because "In the Home app, Wi-Fi information for cameras and doorbells can’t be updated, so you’ll need to factory reset your device and set it up again in the app. In most cases, you’ll remove your device from the app and add it back." That's because they have no way to change the Wi-Fi settings except through a factory reset.

This same Google Nest Help page says if you can't re-use your old network name and password, then you need to either use "Remove Device" in the Google Nest app or Google Home app while you are on your old Wi-Fi network, then do a factory reset, and then add it back on the new Wi-Fi network. See the instructions.
Many customers find they can't make the process work because they didn't remove the camera from the Google Home app while they were on the old Wi-Fi network and are now caught with the camera being inaccessible because it has the old Wi-Fi settings. They have to resort to contacting Support and hope they find someone knowledgeable to resolve the dilemma.
