Help create a conversion report by pages with GA4/GTM/Google Data Studio

Job ID: 34054743

Budget: $30 – $250 USD

We're developing a web app in which users can create help sites.

And I want to realize a stat reporting as below

STEP1
Get the data below by GA4&GTM
1) Pageview
2) Session
3) Solved count (The number of solved button pressed by the page viewer)
4) Unsolved count
5) No hit count
6) No hit keywords

STEP2
Show the data in Data Poratal report in charts and tables.
Report can show the data by filter in which admin can select from "whole app data" or "user data" based on account_id.

My chanllenges at the moment:
I don't know how the data portal shows the "solved count" "solved rate" "unsolved count" "unsolved rate" in the report.
I'm not sure of the best tracking settings to be made in the app and GA4/GTM.

Is there anyone who can help us?
