Embedding is when the PDF can be viewed inside a window on the page, to embed a PDF you will need to copy and paste some code, or script to be more precise...
Open up your PDF in Google Drive online in a browser, it will open in View mode, but you need the embed code, to get this, click on the 3 vertical dots (more items) from that drop down menu you can access the Embed item... you'll have to click 'pop out' first to get this option.
Now you can access the Embed item... option:
A bunch of HTML code shows up - select it all and copy it.
Go to the Teamie page you want to embed the pdf file in and click the Link/Embed option, then paste the code you copied from the pdf page into the window and click Done.
