Hi Shavi,

I think the callouts shouldn't be punctuated because they are not complete sentences but object names.
Only "Click to see the menu." is a complete sentence but, for consistency, we can change it to something like "Alert menu".
Not sure that "Number of alerts that fired" is correct because it's one alert here. I think it should be something like "Number of alert firings.
Not sure what the brackets mean in the last callout.

Probably, we can add a green box around Delete?

Probably, we can add a green box around Edit?

Probably, we can add a green box around Show firings?
