The Molly fork of Signal now has a variant that supports UnifiedPush, but it requires a helper called Mollysocket to be installed on a server somewhere. I can't get my head around the (we'll call them 'lean') docs, and I've never encountered such a helper for other UP apps. They just ask what to attach to, and they attach.
Has anyone fought through this?
in the settings if you change notification method from websocket to unified push, the UP settings come up, including a server address (which is what they intend to be used) or some air gap mode that i can't find documented
