Bought, but cannot install office 2019

I bought Office Home & Student from apple.

I follow the instructions to install and receive this message:

"Thanks for buying Office. We've confirmed your purchase, but in order to activate you will need to download a version of Office 2019 for Mac from this link.

This takes me to a site with multiple subscription resolutions, but...I bought this.

How can I install Office 2019? on Catalina 10.15.6
