How to triger manual navigation on focusable widget component

Hi, I have my own focusable widgets (extending user widget only. Not button, not anything else). How can I make manual navigation from it? Just to tell it to “escape” left, right… anything? I want widget to behave same as button when navigation is being done, and use parameters as in the image below.

Thanks

Just to clarify one thing. I was able to create escapes myself (widget references), but I don’t like that approach. Since it’s manual. I would like to use UE embedded mechanic for this.

Any help is appreciated.
