Push Data to PowerBI

Hello,

I am struggling to get PowerBI to do what i want. The documentation is quite extensive and out of date so it is not clear how to proceed as of November 2023.

I want to do the following....

1) Push data from my web app to PowerBI.

2) View data in a dashboard or chart.

I am having difficulty understand how to set this up.

First i tried to use this tutorial, however it appears to be out of date.

https://learn.microsoft.com/en-us/power-query/dataflows/load-dataflow-metadata-into-power-bi-dataset

Can anyone point me to a simple explanation of how to achieve what i want to achieve with PowerBI? 

Regards,

T
