Customize jitsi UI in electron app...Screenshare implementation

hai . I want to customise jitsi UI in our electron app. we are using libjitsimeet api in our application. But when trying to create localtracks for desktop in electron app , it is not working.
As far as i have searched for electron , jitsi-meet-electron-utils is used for screen sharing which will work only on iframe api… How to acheive this using libjitsi meet .Thanks
