Chat Group Push Notifications -- How to remove the email of message sender?

[Maksidaa]

I’ve got the chat template Robert made and it’s great. I want to send push notifications when a new message is submitted, and I want the notification to be sent to everyone in the chat except for the person that submitted the message. If I have a column of all chat participants emails, what kind of column can I use to remove the message sender email from the participants email list?

You can use the Remove Element column.
You will need to first convert your list to an array using a Split Text column, then remove the element, then convert it back to a list with a Joined List column.

Thanks! I figured out the process up to creating the array and removing the element, but could not figure out converting it back to a list.
