Make INSERT on external keyboard useful in vim

[Hr46ph]

Searched high and low but the best I could find are these:
https://apple.stackexchange.com/questions/301192/how-to-use-the-insert-key-on-an-external-keyboard-with-macos

and a figure 2-10 on page 2-43:
https://developer.apple.com/library/archive/documentation/mac/pdf/MacintoshToolboxEssentials.pdf

Karabiner shows the key:

So the question after all is, what is the best option to make this key useful in vim (terminal) as a toggle for the vim command modes insert and replace?

Thanks in advance!
