Allowing Spotfire Account to be able to access SharePoint(other resources) that require authentication

Good day,

Currently I've a need to display images from a SharePoint (SP) library into a scatter plot.

Service account running the Spotfire services has read grant on SP library.

Challenge here is that, when datapoints are selected on a scatter plot, images fail to render. And this is happening because SP is expecting login credentials to be entered to authenticate the request. Spotfire doens't offer any such mechanism at the moment.

Provisioning this fucntionality to prompt for logins in Spotfire would not only address this scenario but for sure for very many similar resources that require such authentication.

Thank you.
