Trying to locate Tools menu item

Description

I am trying to add a PayPal button to my WordPress.com site
I was trying to follow the advice here (« Method 2: Manually Adding a PayPal Button in WordPress ») which begins:
« Start by logging in to your PayPal account, and click on the Tools menu item. On the next page, click on the PayPal buttons icon ».
However I cannot see the Tools menu item anywhere when I log into PayPal. The only menu items visible are as follows:
Summary / Activity / Send & Request / Wallet / Offers / Help
Any advice welcome
Thank you
