PowerBI and PowerBI

[Hd_212021]

Hi users , I have developed a power-bi dashboard , where it contains a table of three columns , My agenda is has below :

1. I need to add one more column to the existing table as "Comments section"

2 . In power bi , end users cannot add Comments on dashboard so I need to integrate with Power App , where a end users can add  comments and those comments should replicate  on "Comments section " of power bi dashboard.

I request everyone to help in Creating fourth column in the table and Integration part with the powerapps , At the end , the whole data should be saved in sharepoint.

your advise would be very help for me , Thank you in advance.
