I found the plugin, as follows;

Control>Help button>View plugins>Zap-history browser> By confirming the option, the plugin's installation page is reached.

When I look at the device, it does not appear in the add-ons list and it is not in any section in the menu>installation path.

Thank you for your work.
After your last post, I installed this plugin on my device.
I see that it is installed on the device using the Dreambox Control Center DCC.
But I can't find the plugin on the device. It doesn't appear in the plugins list.
Is there…
