Convert images to grayscale or blak and white

[Hilario]

There are so many tools in Screenshot
I wondering if there is an option to transform a colour picture ot grayscale o black and white.
I tried with "enhance colour and contrast" but don't find any adjustement.
Anyu suggestion?

I finally found the option in SpecialFX2 > Adjust Colour Depth > Grayscale
It was easy .. .but not able to find it for long.
