Call Standard Display Maintenance Order App from another Ui5 application

Hello Everyone,

We have created our custom UI5 application. In one of the functionality we would like to connect to FIORI display maintenance order application from other on premise system. We have created the destination between our cloud environment and on premise system. Cloud connector is configured. Now we are trying to open the app with url but this required VPN connection which we would like to avoid VPN connection. How can we call that Fiori application url from our UI5 app.

Regards, MS
