I find this an important tool for maintaining navigation templates and would like to have it made functional again as soon as possible.

Actually, I think the dates for accepting/rejecting my request has passed already. I guess the delay is due to the issue T222255.

Does that mean the tool was run externally by just using db?

I'm just checking if the tool has any secret data that should be removed.

Mentioned in SAL (#wikimedia-cloud) [2019-05-17T17:49:41Z] <zhuyifei1999_> Granting Adithyak1997 tool maintainer access T220272

Can I post the request for having a co-maintainer be posted here?

Yes, please do. :-)
Ideally include some details about what kind of skillsets you'd like the co-maintainer to have, to balance out whatever you still need to learn. That way you can find the best co-maintainer(s).
