Push values into the data layer

[ghost]

Hello,
I would like to add a custom dimension to Google Analytics. According to some tutorials, before I get a custom dimension in GA4, I have to push it by the data layer in GTM (for example here is described how to do that https://mixedanalytics.com/blog/ga-gtm-datalayer-custom-dimensions/).

I use angular-google-tag-manager in my implementation, is there any way to push value to the data layer in this implementation?

Best Regards

I investigated and found that google-tag-manager-service provides access to the data layer.
this.googleTagManagerService.getDataLayer()

I'm closing the issue.
