Fusion EL expression for APEX application integration unsupported now

We are integrating the APEX application in page group so for that in sandbox structure we are having option of Destination for Web Application for Apex and earlier we were using expression as
f?p=109:9999:::::P9999_JWT_TOKEN,P9999_URL,P9999_READ_ONLY_ROLE,P9999_ADMIN_ROLE,P9999_LOGIN_TYPE:#{applCoreSecuredToken.trustToken},#{facesContext.externalContext.request.serverName},SAMPLE_APP_VIEW_ONLY,SAMPLE_APPLICATION,SAAS  

But after redwood updation this EL expression is not supported now by oracle. So after going through the Oracle docs I found alternate of #{facesContext.externalContext.request.serverName} as #{EndPointProvider.externalEndpointByAppShortName['ORA_FSCM_UIAPP']} but the issue is with this change Iam getting https:// with the URL of host due to which APEX application is not working so is there any way to replace the unsupported EL expression and it should not give me https:// rather i should only get fusion base url.
