How to refresh token before it expires (using User Owns Data app sample from power bi embedded)

[sfdomingues]

I have a sample app .sln that I downloaded from after registering an app in power bi embedded using User Owns Data Approach. The only thing I want to do with this is to show a report of mine in a smarttv and let the report be there forever without prompting for login ever again. So in my app's code I want to somehow refresh the access token periodically before it expires. I've seen the documentation: https://learn.microsoft.com/en-us/javascript/api/overview/powerbi/refresh-token

I believe the section "Automatically refresh token example" is what I'm looking for but this isn't enough help for me, they provide an imcomplete "getNewAccessToken" that I have no idea how to complete or where to call it. I dont understand cs code or javascript, but with a bit of help I think I would be able to do this. Can I get any help from you?

Hi @sfdomingues 

For security reasons, access tokens have a limited lifetime.

To maintain continuous access to Power BI reports without manual intervention, you need to implement a mechanism to automatically refresh the access token before it expires.

I found the following documentation for you that may be helpful.
