Each of my projects is related to a particular company and I need to bring in some stock charts and other custom reports for the company for the user to see (and maybe interact with - e.g. save comments.)  Is there a way to do this type of integration? I have created a custom field (of type "link", named "Design" -- see below) and using webhooks and APIs, I can populate its value, but when the user clicks the link, they go to a separate browser tab, I would like them to stay "within OpenProject" for a better experience, perhaps as a pop-up window or any other way.  If anyone has done this type of integration, it would be very helpful for me.  I would also like to learn about SSO and other related topics but the basic task is to just render a view from an external web server within the context of the project.  Thank you!
