xibo-API problem to add widget to layout

[MarkMiura]

Hello, I am currently developing my own application using the xibo-API.
I would like to paste a wedget in the layout, but I can’t find the corresponding endpoint.
I can add the wedget to the playlist, but I can’t seem to do that for the layout using the API.
Also, even if I put the wedget on the layout by the CMS Editor, the schema returned by the get /layout api has no information about the wedget.
It appears that the wedget is in a reigion structure, but I am not currently using reigion, so I cannot check the wedget.
Please someone help me.

My problem is very simple:
how can I add a widget to my layout by means of the API?
The screenshot shows the situation done in the CMS editor.

I cannot find a way to do this by the API.
Can someone please advise me how to do this?
