Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval'

[oussama-he]

I'm trying to add an anchor tag on tweet cards in Twitter site using content-script, but I get this error:

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline' https://*.twimg.com https://recaptcha.net/recaptcha/ https://www.google.com/recaptcha/ https://www.gstatic.com/recaptcha/ https://www.google-analytics.com https://twitter.com https://app.link https://accounts.google.com/gsi/client https://appleid.cdn-apple.com/appleauth/static/jsapi/appleid/1/en_US/appleid.auth.js  'nonce-YmYwM2M5YTgtOTJmMS00OWY0LTk0OGUtNDY1NjdjNTI3NDc1'".

My code in the content-script.js file looks like this:

const replyDom = document.querySelectorAll("[data-testid='reply']")

for(let element of replyDom) {
  let anchor = document.createElement('a')
  anchor.text = "save"
  element.parentElement.parentElement.parentElement.append(anchor)
}
