Custom Formatter for Read-Only Fields conditional based on other columns

Hello!

Does anyone know if it's possible with the fieldsettings, readonly formatting, to make it conditional based on a Person field?  It's a multi people field if that makes a difference? I ideally want to make certain fields read only based on who is viewing it (without having to use a Power App customised form!).

This is what I want (but I know the syntax is likely all wrong!) but not sure if it's possible to use an IF statement with boolean statements?

{

"sections": [

{}

],

"fieldsettings": [

{

"name": "Comments",

"readonly": "=if([$People.email] == me, false, true)"

}

]

}
