I try to send email with node.js by using sendGrid but the email sent always being hidden as shown:

nodejs code:

 const msg = {
     to: 'example@gmail.com',
     from: 'example@example.app',
     subject: 'example: quotation email',
     text: msgText,
     html: "<style>.tab {padding-left: 18xp;}</style>" + msgText ,
}
console.log(msg);
sendgrid
     .send(msg)
     .then((resp) => {
         console.log('Email sent: \n', resp)
     })
     .catch((error) => {
         console.error(error)
 })

NOTE: the message sent successfully and when I click the 3 dots the message shows then, but I want to shows it without let the user to do anything

How can I let my html email content in emails body appears as how other companies did without being hidden?
