how can I read the parameter on UI5 program?

<Question>: How can I read the parameter in URL on UI5 program when I click ‘Open Task’ button of approval menu in Fiori inbox?

• Settings

          1) Tcode : SWFVISU

          2) I created a new target in Fiori

          3) Screenshot of an executed result on inbox

          --> The Workitem is specified as parameter ccc=00000006297, but I can’t get this parameter on UI5 program.

          4) Final URL

http://XXXXXXX:8020/sap/bc/ui5_ui5/ui2/ushell/shells/abap/FioriLaunchpad.html?sap-client=100&sap-language=EN&sap-sec_session_created=X#ZDEMO2_10C-display?ccc=000000006297&openMode=external

     So what I want to know is how I can read the parameter ‘ccc’ in above URL on UI5 program.
