Jetpack Comments Section – 'mandatory' text

Hi guys,

I’m having an absolute nightmare trying to figure this out. I just can’t find it hidden in any code at all.

I have jetpack comments installed (here’s a sample blog: https://www.vaguedirection.com/a-cheat-sheet-for-life/) and would love to change the text that reads ‘Make sure you fill in all mandatory fields’.

Can anyone help?

Many, many thanks!
Dave
