Import UI5-App within SAP Launchpad Service from Standalone Approuter with shell access

Hello everyone,

we have developed several UI5 applications and deployed them with a standalone approuter on the BTP. We are currently using the SAP Portal Service, but will soon switch to the SAP Launchpad Service.

Our apps are currently integrated via a destination and the SAPUI5 component name so that we can access the shell and functionalities such as cross-application navigation. As far as we know, an FLP module is required for the standalone approuter to do so. With the switch to the SAP Launchpad service, however, the FLP module will no longer be available, as the required service instance is of the type "portal".

My question is, which possibility is there to continue using the standalone approuter and still be able to access the shell and e.g. CrossApplicationNavigation when using the SAP Launchpad Service?
