Is it possible to combine may helpers in a template

[olivier34000]

I saved in a key of the state a json string which represents a object. It's the payload of a request

I I creates a paragraph I filled the value in javascript with

const payload = JSON.parse($("State.mykey"))
return payload['name']

However in text the following syntax does not work

{{ get name (JSONparse [state].[mykey]) }} 

I'm not a specialist of handlebar. So I would like if it's my syntax or it's not possible
