Timeline - help with linking document and popping up properly

Hi, I love the Timeline feature, especially linking a PDF or another H5P activity on it. However I am having some problems having the PDF appeared where I like it. I can see the popup option, and I tried the different options to have it opened on a separate window tab. But it doesn't work on the Moodle. Alternatively, I can link it directly to the PDF itself, but I prefer to link to where the file sits on Moodle so that I don't have to update the link everytime I change the file. Please advise on how I can do this.
