How To Get Customer To See Just Their Own Data In The App - PowerBI Embedded

Hello,

I've got a repeating question on PowerBI - and that is how do we achieve compartmentalizing analytics published into an app in PowerBI Embedded. What that means is - how do i get Customer A seeing just his data and visual and not that of Customer B when we embed analytics into our application.

Is this achievable with PowerBI Embedded?

I am intermediate PowerBI engineer so please pardon my ignorance.

Thanks in advance!
