Configuring a Notifications Automation using AWS (SMS)

Hey all - looking for support with a #notifications automation. Inside this automation, I’ve enabled push through the HA companion app, works like a charm. I also want to enable SMS alerts via AWS. Found a few blog posts about this, but I’m missing something…the AWS config connects successfully, but I get an error when I try to execute. I think the ‘target’ is set incorrectly…can anyone help?
Potential the credential config need tweaking too…but cannot confirm, no errors on that side.

Here’s what I have in the target in the notification: arn:aws:sns:us-east-2:061051259699:HomeAlerts

I’m getting this error in the Logs:
