Mongo access and setup parameters

If I want to get access to mongodb database I might have to change a few parameters (right now it binds to 127.0.0.1 and port 27019 etc. Will not blow things up but have a few simple questions.

When I start and stop wekan ... does that start and stop mongo (can't find that in the scripts), meaning I stop wekan, make an edit in mongo and then restart wekan and if it works , great, and if not rollback and try again?

I see the process running mongo and see mongo-control scripting and its all referencing env variables in that script and its is in /snap/wekan/714/bin. I see a file called "config" where it appears all those env values are set. Is that where I do minor editing, and when I restart wekan, itsrestarts mongodb and rereads those variables?

All I want to do is to be able to read the mongodb directly on occasion (not change anything) through a local vpc secure server to one IP address while doing api development. I suspect that if I open up port 27019 to a single ip address and add a login. or use the wekan login, which I believe is documented in the installation notes, I probably would not be able to see that mongodb remotely as bound.

Oh another question. I logged into Mongo locally on the terminal (on the wekan server) and it let me in without auth. Is that correct? You run mongo without authentication enabled and leave it away from everything else for security?

If so, if I did want to expose Mongo inside of wekan even with a single ip and only for a short while, I would want to enable auth in mongo. If so where can I edit the wekan config to use/add creds?

If it is already under auth then disregard my question. I wanted to confirm that the binding was why I could not log in remotely which made me want to confirm the creds locally first..... Assumed 0 or no bind vs 127.
