First use, eww in labwc(wayland) not starting

[dancaer69]

I just installed eww to use with labwc from aur, but I cannot get it to start. I tried to follow the example in documentation which doesn't work. After google searching I found that need to modified for wayland use and with help of chatgpt I have modified the eww.yuck and now has these conents:
(defwindow example

  :monitor 0
  :geometry (geometry :x "0%"
                      :y "20px"
                      :width "90%"
                      :height "60px"
                      :anchor "top center")
  :stacking "fg"
  :reserve (struts :distance "40px" :side "top")
  :windowtype "dock"
  :exclusive true
  :focusable true
  "example content")

I also have a eww.scss with these contents:

// WINDOW RELATED CSS
.bg {
  background-color: #1E222A;
  border: 2px solid #80A0C0;
}

in case needed for eww to work.
But when I try to start it with:
eww open example
I get the following error:

failed to open window `example`

Caused by:
    Failed to get x11 window for gtk window

Any help?
UPDATE:
The package I installed didn't have support for wayland. I replaced it with another and now works fine.

Just saying, the property :windowtype is for X11 only.
