Cross graph embed?

I really like the cross-graph linking released in 0.6.6, is it possible to embed the blocks or page from another graph?

I did played around with it by relacing with the url of the block from a foreign graph, but it didn’t work, instead of pointing to the right page in another graph, it created a new page locally.
{{embed ((<block uuid>))}}
{{embed ((logseq://graph/<graph name>?block-id=<block uuid>))}}
