managing multiple refreshes for customer embedded solution

Hi,

I am using Power Bi API's for refreshing the dataset and managing the Parameter update task for my React app.

I want to ask and understand how when different logged in users will come on the system and their specific parameters like creation_id, building Id etc will go to the API request and update the dataset in Power Bi, Will all users be able to see their own data or how the things will be managed as I want each user should be seeing their data only.

Please guide me on this it is becoming headache now.

Thanks & Regards
