Adding a link into the Geoprocessing tool widget to open a new window

[DougBrowning]

Trying to add a hyperlink into the label of the geoprocessing tool to launch a PDF help file and no matter what I try it opens in the same window.

I think based on this post it is a no go?  https://community.esri.com/t5/arcgis-web-appbuilder-questions/open-link-in-new-window-web-app-builde...

I want to do this since the page that opens up from the built in Help link here does not support HTML links.  Which is weird since I set it in the metadata as a link and it works in Pro fine.  Weird to have a help page that cannot have links.  (As a bonus the formatting goes nutso when opened from Pro.)

Any ideas?  thanks
