Broken federation between hubzilla forum and lemmy?

I can comment and interact with communities on lemmy but the reverse seem to be not fully working. I have a test community test@utsukta.org which i can subscribe from lemmy but any public post i make on this forum do not get delivered to the users subscribed on lemmy. Is there any setting that may be misconfigured? or is this a federation bug?

@Saiwal Try sending your posts to your test community as a DM

Ah... Okay... I do not have a lemmy account...

Does it work from other activitypub platforms?

I have not tried from any other platforms yet.

The incompatibility is probably because lemmy makes all posts public and hubzilla forums handle posts in a different way. have fiddled with privacy settings but couldn't manage to make it work.

@Saiwal AFAIK, it's possible to post to a Hubzilla forum from e.g. Mastodon by @-mentioning the forum in a public post. This is a convenience workaround so that users of Mastodon etc. can post to Hubzilla forums like they post to any other group actor such as a Guppe group instead of having to jump through hoops and learn to post in a way that's unnatural to them.

So either the issue is that Hubzilla expects forums to be mentioned from ActivityPub, but Lemmy doesn't mention Hubzilla forums, or posting to a Hubzilla forum from something ActivityPub-based is b0rked, but nobody knows because nobody ever posts to a Hubzilla forum from something ActivityPub-based.

Only a guess, but my guess is that it doesn't work because Hubzilla expects either a mention of sorts or limited permissions. Zot/Nomad channels must send what amounts to a DM, but all three ways of sending DMs are valid. For ActivityPub-based accounts (not sure about Friendica accounts and Forte channels here), it's sufficient to mention the forum channel in a public post. But Lemmy accounts don't seem to do any of this.
