Which is best adding or tool for doing write back operations in power BI

Hi Anonymous 

To implement the write-back functionality, we create a canvas app in Power Apps from a Power BI report. The app captures data from the Power BI report and creates a gallery out of it; at the same time, the app is connected to the same data source as the one feeding Power BI – we are going to use this to write the data.

Please refer to the following document for more information.
