Charts metadata db URI

Hi.
I have charts installed and running by previous admin and ssh access.
There is no locally Mongo installed and I know where is Data Source located.
How to figure out metadata location and URI for running application?
The issue is that the owner of all the charts is None, so I can not edit it, tried admin/all the users without result.
It seems for me I need to edit metadata manually and reassign charts to either me or admin user.

version is: quay.io/mongodb/charts:19.12.1

update:
I found the lines in my charts-docker-swarm-19.12.1.yml:

secrets:
  charts-mongodb-uri:
    external: true

so, how to extract charts-mongodb-uri and view charts-mongodb-uri?
