iOS/iPadOS launching external app

I’m trying to configure an entry to launch an external URI (in this case, Jump Desktop) using the iPadOS RDM client. The only way I can see to do this is using a web browser entry, however I’m having some issues getting it working.

When I create a new connection entry and enter the URI as jump://etc, by default the internal browser opens and prepends http:// to the entry, which of course fails. When I set the connection to display externally, Safari opens but the colon is stripped and Safari fails to load “jump//etc”. However, from within the connection settings, if I click ‘navigate URL’, it correctly launches Jump Desktop.

It also doesn’t seem to be passing variables in the URI- I saw another thread on the forum where this was fixed in the desktop client but perhaps this needs to be fixed on the iOS/iPadOS client as well?

Is there some other way I’m missing to achieve this?

Thanks
