Question regarding bags in custom UIs

[Khamul]

I tried to show bagslots in my custom UI. But instead of showing the correct bags, there are only 6 clickable buttons. Any chance to use bagslots in an ui which is NOT called eq2ui_inventory_inventory.xml.

Is there a way to show the inventory window with correct bagslots?
Doing a /show_window inventory.inventory will not work for the bagslots.

Sorry for my bad english and many thanks in advance for your help.
