Description
When adding custom parameters to the configuration tag in GTM, the param values are not included in the auto events, such as "session_start". For example, we are using a parameter to store what market the visitor is viewing on a global website, and now we can't filter out sessions based on a single market based on "session_start" events.
Expected Behavior:
All parameters that are included in the configuration tag should also be included in the auto events.
Steps to Reproduce:
> Add a custom parameter to the configuration tag in GTM.
> Open an exploration report in GA4 and combine Event name and the custom parameter in rows and filter on Event name equals "session_start". You will see no values in the custom parameter.
