New user counts, landing pages and traffic medium & source

[Farsana]

Team,

1. I want to extract and calculate information related to new user counts, landing pages and traffic medium & source, what are the parameters i should activate from GA4 connector with respect to the table "RunTimeRealReport" and "RunReport".
2. It also highlighted  that for runtime real report we can choose only  4 fields and for RunReport max upto 9 fields. So in case if user requirement to add more columns any options/alternatives we have?

Thanks
