Any progress in embedded url? (?embed=true to hide headers in canvas workpad)


I've used to render kibana dashboards usually and embed=true works well.
but this time, i want to render my es index as Table and found that "canvas" fits for me.

so, i made url and put it in iframe but ?embed=true doesn't work.

as i searched,
topic embed url is in icebox :cold_face:

is there any way to hide headers?

http://<host_url>/s/<space_name>/app/dashboards#/view/<dashboard_id>?embed=true <- this one works

http://<host_url>/s/<space_name>/app/canvas/workpad/<workpad_id>?embed=true <- this one does not works

Zero Response Here :cold_sweat:
