"Cannot find reference 'XMLTestRunner' in 'xmlrunner'"

Although I have installed xmlrunner successfully (this is what I get from the logs of my IDE: 19/11/2020 09:37 Packages installed successfully: Installed packages: 'unittest-xml-reporting') I get the following error message: "Cannot find reference 'XMLTestRunner' in 'xmlrunner'" Here's my code, thank you in advance for your time and consideration (last line is the one relevant here):
