Using PBI report for simple database crud operations

Hey,

Was wondering if it would be possible/recommended to reliably use PBI desktop for simple crud operations via API calls, not even full crud, but simply read and update. 

We have a couple of legacy apps for a product manufacturing step, and I would love to drop those. Im talking about 3-5 calls a minute all day. Normal process is to fetch some data based on a barcode scan, then add some numbers and little bit of text.

If so, whats better - azure functions or own backend service? What to consider for authorization (employees work from pcs that were migrated to azure).

Have a great year
