Overlay won't show up in preview

I’m working on my first story and everything is going well. I have gotten up to a point where I need to use my first overlay! It is SELFIE FEMALE 1 and I’m trying to make it look like my character got a text message. I inserted the script command, but during the preview on my phone AND computer, it won’t show up. Here is the script; I think It’s correct.

@VALERIA is idle_read_phone_neutral

@overlay SELFIE FEMALE 1 create

Thank you.
