Automating update dependencies

We have hub & spoke setup for Looker and utilize remote_dependency in all projects. Trying to make it easier on devs by automating the Update Dependencies step in downstream projects when they merge a PR in an upstream project.

Feels like the Lock All api method might work but I’m not 100% clear on what it does. Does anyone if this is the just the equivalent of a user updating dependencies in a dev branch (ie modifying manifest_lock.lkml file) but still requires a PR to finish update?
