How to use OCR in Mail to save a ton of typing

I figured there was an AppleScript solution, but I knew it was beyond me, and I hadn't played much with OCR so I thought it'd be fun :). However, the script doesn't seem to work (Sonoma, KM 11.0.3), as it throws this error with a message selected:

Mail got an error: message viewer 1 doesn’t understand the “theName” message.

So I asked my LLM-of-the-day, and it said that you can't assign theName in that way. It suggested this, which works:

tell application "Mail"
	set AppleScript's text item delimiters to " - "
	tell message viewer 1
		set selectedMessage to item 1 of (get selected messages)
		set subjectText to subject of selectedMessage
		set theName to text item 2 of subjectText
	end tell
end tell
return theName

I have no idea why it fails or why it works, but it does work in the LLM-provided version :).

There are only two disadvantages that I see to AppleScript. The first is that the message has to be selected, which just means I have to click on it before running the macro (not a huge issue). The second is that it's (shockingly, to me) marginally slower than doing OCR, probably due to the overhead of AppleScript.

The AppleScript method takes ~0.17 seconds; the OCR method takes ~0.12, despite having to do a screen capture, OCR, and regex to extract the name. Wild.

Thank you for the AppleScript version—it's probably also much more reliable than my OCR method, but I had fun figuring that one out :).
