Hello~!
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, https://github.com/elastic/kibana/issues/168126
topic embed url is in icebox 
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
