Custom app mappable parameters. Text, multiline

Hello,

I am building a custom app and am testing out fields in mappable parameters.

I have a field where I need more than 1 line but I see the multiline option is deprecated. How do I set the code up below to have more of a text area look?

[
   {
        "name": "yourQuery",      
        "type": "text",   
        "label": "Your query", 
        "required": true
    } 
]
