Replace multiple String quotes

Question

I am trying to replace the following and keep getting an error
"browser":{"enabled_labs_experiments":[],"last_redirect_origin":""
with
"browser":{"enabled_labs_experiments":["same-site-by-default-cookies@2"],"last_redirect_origin":""
I am using
(Get-content "$env:USERPROFILE\AppData\Local\Google\Chrome\User Data\local state") -replace '"browser":{"enabled_labs_experiments":[],"last_redirect_origin":"', '"browser":{"enabled_labs_experiments":["same-site-by-default-cookies@2"],"last_redirect_origin":""'
I am getting
The regular expression pattern "browser":{"enabled_labs_experiments":[],"last_redirect_origin":" is not valid.

Hi,

The "-replace" operator uses regular expressions to find the specified pattern so the escape character "\" needs to be prepended to the brackets.

(Get-content "$env:USERPROFILE\AppData\Local\Google\Chrome\User Data\local state") -replace '"browser":\{"enabled_labs_experiments":\[],"last_redirect_origin":"', '"browser":{"enabled_labs_experiments":["same-site-by-default-cookies@2"],"last_redirect_origin":""'
