Sparrow Terminal on umbel?

Hey is it possible install Sparrow terminal on Umbrel via the community app store i don’t see it listed. Is there anything i can to do have it added, or add it manually via the manual app install?
The reason i am eager to do is is because i read this article tweeted out by which outlines how to use whirlpool from an iPhone.

Hello man,
There is not app in the store right now, but it’s a good idea.

Moreover, you can SSH through your umbrel, create a new user, install sparrow server and run it throught it! Little bit techy but it works fine.
