Add "block" to right click context menu in messages
I'm getting 5-10 scammers a day messaging me and trying to get me to donate to their fake political candidates, promising things like "1500% MATCH!! DONATE NOW!". Can I edit the right-click context menu to just add "block sender" so I don't have to waste time with each individual scammer? I know it's possible in Winblows to change context menus but I haven't done it before on MacOS. Thanks in advance.
Mac mini, macOS 12.5
