How could I make placeholders work with this script?

tell application id "DNtp"
	set templatePath to ("/Users/jhc/Library/Application Support/DEVONthink 3/Templates.noindex/Productivity/Fleeting Note.dtTemplate/English.lproj/Fleeting Note.md")
	import templatePath to incoming group
end tell

Hi, I’m new to apple script and this is what I figure out this afternoon. What I want to achieve is to create a new markdown note in my inbox with a custom template (placeholders included). What I fail to achieve is to make the placeholder inside the note work and still don’t understand how to insert placeholders in the template name. Does anyone know how to do that? Thank you very much.
