Translate Email Template with Subject: Email Changed

Hi,

I did translate all known words in UM that I’m aware of. Today I try to change email address of mine and received email confirmation with subject: Email Changed.

The body text as below:

Hi username,

This notice confirms that your email address on Website_Name was changed to new_name@newemail,com.

If you did not change your email, please contact the Site Administrator at
admin@domain,com

This email has been sent to old_name@oldemail,com

Regards,

I try to search this email but can’t find it.
I also open all email templates under this folder /ultimate-member/templates/email but still can’t find it.

I believe it’s not email sent by core WP but UM.
All other email from UM is working perfect.

Please help
TIA
