Hello,

I have submitted my app to Edu App Center and trying to pass params by url https://www.eduappcenter.com/configurations/92o995pg5z4y84fg.xml?channel=my-channel&hostname=my-host

I want query params

• to be used in custom properties
• to be used in launch_url

Some apps that support query params properly:

• redirect tool https://www.eduappcenter.com/apps/63
• EvaSys https://www.eduappcenter.com/apps/870

Sorry to say there are no docs, examples, etc.

Does anybody knows how to make it work?
