I’m having the exact same problem. The plugin seems to describe a URL format that you can’t actually choose in wordpress. For example, normal shortcode link might be:
https://site.com/?page-id=1234
Adding a parameter like
https://site.com/?page-id=1234&value=test
breaks the link. Likewise changing the permalink structure ie
https://site.com/page/
And adding the parameter as
https://site.com/page/?value=test
also breaks in just the same way.
Documentation suggests URLs like https://site.com/page?value=test which is just not possible.
Sadly not holding out much hope for a solution as it seems to be scarcely attended to ??
