Email link open [closed]

I built a web view mobile app. After the app has been installed on a mobile phone, whenever a password reset link is sent to a user email to reset password, the link proceeds to open on a web browser instead of popping out and option for the link to be open in app. I used phpmailer to send the message with the following code

$message = "Hi Adeyemi <p>We received a request to reset the password for your account. You can reset your password by clicking the link below:</p><p>https://investwithbth.com/app/reset-password.php?token=78uiyt65redfty78iuhj</p><p>If you didn’t request a password reset, you can safely ignore this email, no changes have been made to your account.</p><p>If you have any questions or need further assistance, feel free to contact our support team.</p><p>Thanks</p>";
