Katalon sendMail

Hello Everyone

Is there anyone already tried to sendMail on multiple email address in console mode execution ?

I already try this sample codes below but still not working for me

-sendMail="sample1@mail.com, sample2@mail.com"
-sendMail="[sample1@mail.com, sample2@mail.com]"
-sendMail="[‘sample1@mail.com’, ‘sample2@mail.com’]"
-sendMail="sample1@mail.com sample2@mail.com"

Thanks in advance
