How to set a sender’s name of notification email to be my own name

Hi. I have set “sending notification mail on form submission” function to my custom form along with Wix code tutorial ( https://support.wix.com/en/article/how-to-send-an-email-on-form-submission ).

With the codes of this tutorial, the sender’s name of the email delivered on submission is my email address. NOT my own name!

Could someone kindly let me know how to set the sender’s name to be my own name?
