I look for the URL which requests an "all community forums" view as a deep link for a given community UUID.
For ATOM, that is /forums/atom/topics?communityUuid=[communityUuid].
But for HTML, I cannot find an appropriate URL.
The URL should request and render all forums of a given community. This is a view which can be manually navigated to by displaying Forums of a Community and switching from the Topics tab to the Forums tab.
I believe you are looking for /forums/atom/forums/my?communityUuid={communityUuid}
