Untranslatable string?

Hi,

I’ve started updating the Czech localisation of Mailspring and came across an untranslatable string: “NOTE:”.
I’ve attached a screenshot for reference.

I couldn’t find this string in the original en.json resource file, so I’m wondering – is it hardcoded, or is there a way to translate it?

Thanks in advance!
