Hi @abouchaalaBAIT ,
I suggest to use a Power BI DirectQuery dataset in a Dashboard for this purpose.
1. Create a new Power BI Dataset in Power BI Desktop using a SQL Server DirectQuery (TDS endpoint) to your environment.
2. Use a simple "select count(*) alias_column from dataverse_table;" as a SQL Statement

3. Import the created dataset into Power BI Workspace and save. This will create a new Power BI Dashboard for you.
4. Go to Dashboards > New > Power BI Dashboard.

5. Select the workspace you created the Power BI Dashboard with the DirectQuery datasource and click on Save.
6. When the Dashboard has been created, you can open the report and you will see the total number of records in the report. The number is based on the privileges the user has. A system administrator will see all rows in the table being returned.

Best regards
Hauke
