I see that https://archive.pulumi.com/ has "Join Slack" button at the top right corner. How to achieve that? It should be "Join Discord" in our case. Now I see "Log in" and "Sign up" buttons to linen itself.

We had a custom invitation url in the past, so our premium customers could point directly to slack and discord. We're still trying to figure out in which direction build the platform out so we're experimenting with being a chat platform on it's own right now and that feature is not there anymore. We'd like to invite people to use the platform on daily basis.

Maybe you can consider continuing to support both use cases? The Slack/Discord archive is a really killer feature for many companies. Until you have video calls, bots, and tons of integrations, it's unlikely you'll be able to fully replace Slack or Discord.

Thanks for the honest feedback, we know that we're still behind. We have some internal discussions about this particular feature, will keep you posted if we decide to bring it back.

Just to add a +1 for this, I came here to ask the same question (I had spotted it on https://slack-chats.kotlinlang.org). I was hoping to use Linen as a Slack archive and have the chat functionality as a backup / "maybe one day" feature.
