Trigger VCS Project Settings update after successfull build

I have a project which settings are versionned in Kotlin DSL format. Let's call this project project A.

I have another project B outside of project A's tree, that contains a build configuration that creates subprojects in projects A i.e.:

• B's attached VCS is the VCS configured on A as VCS Project Settings. So TC checks out A's project settings on the agent.
• In a custom agent tool :

1. Create a kotlin dsl project folder and files depending on parameters (via a custom agent tool)
2. Run some unit test on the created kotlin dsl files
3. Commit and push the changes to the VCS

Now I would like to automatically ask TC to pull the project settings changes and apply them in project A.

For now I do it manually from the following view: Versionned Settings -> Change Log -> "Check for Changes" button.

Is there a way to trigger it from build B ?

I've seen in the manual that line (https://confluence.jetbrains.com/display/TCD10/Storing+Project+Settings+in+Version+Control#StoringProjectSettingsinVersionControl-CommittingCurrentProjectSettingstoVCSForcingSynch):

By default, the VCS trigger will ignore such changes. To enable build triggering on a settings commit,  add a trigger rule in the following format: +:root=Settings_root_id;:*

I did not manage to make it work (I replaced the example with the proper root id).
