Wix-fetch send email to multi-addresses at once

Hello there,
I have tried the example code as Velo Tutorial: Sending an Email on Form Submission | Help Center | Wix.com,
And it works just fine,

However, If I try to set recipient as “add1@mail.com;add2@mail.com;add3@mail.com”,
only add1@mail.com received mail,

Is there any way to make it happen?

Take a look here: https://www.wix.com/code/home/forum/product-updates/sending-an-email-on-form-submission%3Fpage%3D2

Thank you Sam !!
It works perfectly !!

So I’ve got WIX code set up so that I’m able to do what is referenced in the article linked above, but it’s showing all email addresses in the TO line separated by semicolons, so each of the recipients can see the others who are included. Is there a way to either (a) send to all email addresses on the BCC line or (b) send to each email individually? Separately, also trying to figure out if there is code that can be edited in the JSW file that would allow an input field on a page on my website determine the FROM email address rather than locking it into a static email address.
