Note that you have to have developer tools enabled in order to see that tab.

It probably goes without saying, but be *extremely* careful with the
things exposed in that browser. It is meant for developers who know what
they're doing to twiddle bits in the memory image. It will let you
easily do damage to your radio without warning. Hopefully it is obvious,
but using that tab definitely voids your CHIRP warranty... :)
