DoF calculator recommendation

I trying to make a note of effective DoF based on different setup.

I ve looked at many, but the closest (useful) one I got is this one

But I can't get it to give an estimate for 1:1 distance

i.e. if I use the following info:

Camera: a6300

FL: 90mm

Aperture: F/2.8

Focusing distance: 280mm (for 1:1)

(all other options left to default)

But it returns: "Focusing distance must be at least four times the focal length"

Are you aware of any alternatives that will allow me to calculate DoF for above scenario?
