core.js:4197 ERROR TypeError: ctx.contact is not a function

[manel00]

Hello, how to fix it? I'm using Ionic 5 and trying to use Email composer but it gives this error

My code:

let contact_TSA = "[email protected]"

let email = {
  to: contact_TSA,
  attachments: [
    'file://assets/icon.png',
  ],
  subject: 'New Request',
  body: "I'm writing you due to",
  isHtml: true
}

// Send a text message using default options
this.emailComposer.open(email);

Thank you!
