The add page button does not have an accessible name

Bug Report

Problematic behavior
The user doesn't know where to find it since it isn't properly labeled.

Expected behavior/code
The code in question is this

<button color="primary" class="sc-34780e96-0 kYJbsY --docs--box-button "><span class="sc-34780e96-0 sc-262648e5-0 iiwUsF foIyfo --docs--icon-bg material-icons-filled">add_box</span></button>

Steps to Reproduce

1. Activate the screen reader NVDA or VoiceOver
2. Tab to the subpage add icon
3. And you will hear "add_box", which has nothing to do with the expected function of the button

Possible Solution
Add a label to the button with an attribute aria-label="Add a subpage"
