MSGEQ7 Audio Analyzer Module's Arduino Library is invalid

I am using Arduino 1.8.13. I am adding the library to my installation and get the following message “Specified folder/zip file does not contain a valid library.”

I am using the library from https://www.dfrobot.com/product-514.html

I have installed many libraries before but this one does not seem to be valid.

Suggestions? Ideas?
