Webpage not displaying in Storyline

Hi Team, 

Hoping someone can help. 

Am trying to get a webpage to open in the same window in Storyline but cannot get it working, I appear to get a frame display error (see attached image). The link itself is to a page on our company SharePoint. 

I dare say this is due to company SharePoint permissions, but does anyone have a work around I can try. I would really like to avoid having the link open in a new window if at all possible. 

 

Thanks, 

Matt
