Sync data between Adobe express document and UI frame (add on)

I can have all the node by use editor.documentRoot to have the id of the node. I want to update value of the text node or mediacontent in the doccument by use the communication api but we cann't update the value by the id if we dont focus it by the mouse click.

• I expect to have the api to update the value nodes but dont select node by the mouseclick or orther by hand.
• I expect to set the name of the node by communication api
