Location Updates via Home Assistant Cloud Webooks, but no remote access enabled?

I have a HA instance connected to Home Assistant Cloud, with remote access disabled. I noticed that in the Home Assistant Cloud Settings > Webhooks, there is an area for each mobile app I have installed. I would like to use these webhooks for the iOS apps to send back location data if possible, as I don’t want to expose my instance through remote access unless necessary. Is this do-able?
