About checking the page indicators included in the content group of Looker Studio

[age8marke]

We have created a content group using the {{Page Path}} regular expression condition in GA4 (GTM).

So, we have listed the following issues and questions when implementing the following settings in the Looker Studio table.

◉Configuration of the Looker Studio table
Dimension: content group / Page Path+Query
Metrics: Sessions / Users / PV / Engagement rate, etc.

◉Problems
・We would like to drill down into the content group dimensions to see the metrics for each page in the content group.
・When I drill down, I get an error message that says "Invalid settings: Invalid combination of metrics and dimensions" and I cannot see the metrics for each page.

◉Question
・What steps should we take to remedy the above problem (drill down into the content group, but not be able to see the indicators for each page)?
