SAPUI5 - Navigate back to Fiori launchpad from custom application

Hello,

I am stucked with a problem. I am developing a custom UI5 application what is deployed to a Fiori Launchpad - the launchpad is running on a gateway system so this is not a cloud solution.

I have a requirement that say user neeed a Quit button in the application. I know there is a Home button to navigate back to Launchpad but the customer insist to his idea that we need a separated Quit button.

I have found CrossApplicationNavigation solution but it is not working for me because sap.ushell is undefined.

history.goback(-1) is not option in our case bacuse it is not working properly in every case.

Do you know any other solution?

Thank you very much!
