We are using an instance of SharePoint Server 2019 (On-Premise) not 365 cloud version. According to the information in the link provided below: https://support.microsoft.com/en-us/office/use-the-document-library-web-part-a9dfecc3-2050-4528-9f00-2c5afc5731b0 Per the instructions (minus images) Add a document library to a page 1. If you want a custom view of your library to appear on your page, create the view. 2. Go to the page where you want to add the library. 3. If your page is not already in edit mode, click Edit at the top right of the page. Hover your mouse above or below an existing web part and you'll see a line with a circled +, like this: 4. Click +, and then select Document Library from the list of web parts. 5. Select the document library you want to put on your page. 6. Click Edit web part on the left side to change the Document library, the View of your library, and the size. You can also display a specific folder in the library by entering the folder name (use a "/" to separate the names of nested folders): 7. When you're done, click Apply. 8. When you're ready, click Publish at the top right of your page. In my environment there is no option to include Folder. There is only Document Library, View, and Size to choose from when making edits. If this is the wrong place to post this please let me know where I can ask the question with an On-Premise solution.
