Custom Clock with PiCorePlayer + jivelite

Hi,
I'm running PicorePlayer 8.0.0 with Jivelite using the official 7" touch screen and trying to use SuperDateTime savescreen.
I found I needed to install first custom clock applet and Custom Clock helper. problem is, after installing Custom Clock applet and rebooting device there is no custom clock under Extras nor available as screen saver.
Any idea how to troubleshoot this? I checked logs but could see nothing. Maybe need to increase level of detail for LMS logs?
PicorePlayer 8.0.0
Squeezelite v1.9.9-1386-pCP

Thanks in advance!
