change wordpress password reset link

Hello,

I have configured Sendgrid to send emails from my website. I have created a subdomain in SendGrid like sg.app.com. The issue is that in the email that WordPress sends to reset the password, I see the URL set in SendGrid. I have used SendGrid in different domain i.e. example.com. How do I change the domain name from the email sent by wp? Also I want to use https:// instead of https://

Someone has requested a password reset for the following account:

Site Name: Example

Username: first.last

If this was a mistake, ignore this email and nothing will happen.

To reset your password, visit the following address:
