Can Org-Roam be used in Logseq?

I’ve heard that Logseq has org capabilities. Can Org-Roam be used in Logseq like in org mode?

Also, can Org-Roam be used across devices while keeping the same data? E.g. iPhone, iPad, Macbook, Windows

There’s already a thread on this. I’ve just posted there: Logseq: FLOSS web outliner, compatible with Org Roam now - #10 by wuqui
