Similar to how a page module can show live pages, the Custom Media element can show almost any page output, given its URL. This is useful for sharing key documents with other team members, all in one place.
To view a document, enter in its URL in the text field and then click on the save button to the right of the text field.
This allows you to import and share Google Sheets, Docs, or anything that has its own URL and is viewable.
There is also a "Notes" button at the top right that allows you to make personal annotations or records that are also viewable to anybody that has access to the plan (such as team members.)
Click the red X at the top right to get back to the main canvas.
