Hi Hilman,
You probably can't download the module as this is built in Mendix 8.13.1 and you try to open it in 10.20.0.
You could start a new project in Mendix 8 import the module and then upgrade the project to Mendix 9 and eventually to Mendix 10. Once you have the project in 10 you can export the module and import it in your own project.
However since this module isn't updated a long time maybe it might be better to look to alternatives, for example: https://marketplace.mendix.com/link/component/235426 this one.
