View Bookmarks In a Web Version of PDF Reader

I'm sorry if my title is confusing but I'm not sure of the correct terminology.

I have a lot of PDF documents that are accessible from OneDrive in Office365. Once the documents are clicked for viewing, they appear in a web version of PDF Reader. It is a very stripped down PDF Reader (see screen shot).

There is no option for viewing bookmarks already pre-established in Adobe Standard. I even changed the default settings to show the bookmark panel when the documnet is opend.

Does anyone know of a way to view bookmarks from this type of PDF Reader?

Clik here to view.

Again I'm sorry for my horrible terminology but any help is much appreciated.

Thank you,
