Power BI Authentication using REST API without GUI using Java (Refresh Token)

Hello,

Currently I am getting Power BI Report from Power BI services with access token and embedding this report into IFrame using Azure AIDL Authentication.

Using this Java Library I am getting an JWT access token and fetching into my Power Bi report.

Below are the problems with this approach:

1) Access token has a short validity of 60 mins. and after that I fetch new access token using refresh token.

2) But the refresh token itself has a validity of 14 days and after that I need to manually log in and update the refresh token manually.

I want to avoid manual log in and wondering if there is any way to make this automatic.

Any suggestions would be appreciated.
