Can I crosspost on Piefed? [Solved : No, you can't]

I'm discovering the threadiverse through a new account and software.
I wanted to crosspost a Lemmy post into another Lemmy community. Can I do this from a Piefed instance?

EDIT : No, you can't. You can only reference another post using a link.

Here is an example of a crosspost btw two Lemmy instances. Piefed only allow to access the link btw them

Here is an example of copy-pasting a link to a Lemmy post into a new Piefed post. There is only the link but no proper crosspost

Note that I attached in my test the post to the software of the poster not of the community.

Right now Piefed voluntarily allow crosspost for bot only as stated by @Rimu here
https://codeberg.org/rimu/pyfedi/issues/206

I've added a feature for a limited form of cross-posting - on any bot-created post, if it hasn't been posted elsewhere yet, there is a cross-posting button. This is most obvious at https://piefed.social/c/[email protected] where a large percentage of the links have already been posted in 'real' communities.

Long-term we will want to have cross-posting on all post types but I don't really want to encourage cross-posting until we handle duplicate posts better, like Mbin does.

Thank you all for helping me figure this out

2nd EDIT: We figure out in the comments a way to get the crosspost pick up by Lemmy but it is only for post having an external reference and it is not picked up by Piefed.
