Although they haven't released things recently, the team is still very actively posting updates that they are focussed on their upcoming releases. And I know myself they're turning away other work to focus on getting it done! So could be a good sign.

It's a very very cool project. However it has been in "perpetual beta" for probably at least 4 years at this point. Kinda similar to BCH Gurus... the "it'll be live soon" has continued for years on end with little delivery. But it's a great concept, I hope they can get it released fully.

Nevermind, I got it to fired up now, excited to give it a try…

Unfortunately not, you can only link for now. Media upload support is probably one of the first things that gets addresses in the next BChat update.
