I can't find the tags panel. Official documentation refers to an older version of Adobe.

Hello all,

    I'm new to Adobe Acrobat Pro and I'd like to create accessible documents. I've read that there exists a "Tags" panel. However, I can't locate it in the current version of Adobe Acrobat Pro I'm using. With the "Tags" panel you can see the structure of a PDF document. Your help will be very much appreciated.

Thanks!
