[Custom Sidebars Pro] Custom sidebar for BuddyPress Group pages

The custom sidebar that I created for the BuddyPress Group pages is not shown, although I attached it in the page that shows the BP Groups.

I have seen 2 similar threads, but they don’t help me that much:

https://premium.wpmudev.org/forums/topic/custom-sidebars-pro-custom-sidebars-pro-to-support-sidebars-for-buddypress-groups: the workaround via the sidebar location setting shows BP options that I don’t see in my site.

https://premium.wpmudev.org/forums/topic/cant-apply-custom-sidebars-to-buddypress-groups: interesting, but how does that work for a multisite where for each site the sidebar id is different?

I am in favor for getting this function supported/added by Sidebars Pro. But for now, what could be a workaround?
