I am developing a custom Power BI visual. In my use case, the visual need to authenticate the users to a third party server with the Oauth2 protocol. When opening the report, every user should have a separate access token connected to this account. So, basically, my need is to save some user specific browser session data.
I know there is the Localstorage API and I am considering this for the future, but the certification and publication path is not something doable right now.
I also tried to use cookies and the typescript built-in sessionstorage object, but none of them work. Also, saving authentication credentials in another server to retrieve them later is not an option, other than ugly.
