How to integrate component to WEB UI

Hello, gurus!

Here is my problem,so I want ask you for advise.

I want to add my z-component to Web UI interface. To do that I've already created a component with Main Window in BSP_WD_CMPWB using wizard, then I've created a view and attach it to my MainWindow. Then I created inbound plug for my MainWindow. But in SPRO->CRM->UI Framework->Technical role definition->Define Work Area Component Repository when choosing my created component I can not select the MainWindow of my component and I get message "Window Z_BSP_TO_EP/MainWindow has not been defined in the loaded Runtime Repository".

Any suggestions how to solve it?
