@Kumar2608, @awalia13 could we get clarification on this issue?
Contrast ratio for focus on checkboxes have been verified as fixed in #1712. For that part of this bug, I believe there is no action item. Can we confirm?

Regarding the last screenshot above, it looks like the buttons at the bottom of the dialog should be a separately filed bug. What does "highlighted control border" mean? Does that mean mouseover/hover?

Cancel button (no mouseover)

Cancel button (mouseover)

Should one or both of these Cancel button states be modified?

The button next to it, Connect, is disabled in these screenshots. Does this also need to have a higher contrast value when disabled?

Thanks for the clarification!

Above "highlighted control border" means control inside that Red border which is "Cancel button" and as per new WCAG2.1 boundary and background of the control should be greater than 3.1
and also disabled controls are not comes under WCAG2.1.
