How i can remove the blue border in Material React Modal?

问题

I'm using this React Material Modal. In the demo examples you can see that when you open the modal, has a blue border.

There's a way to remove it?

I see in the Modal Api that haves the property disableAutoFocus but i'm setting "true" and my modal still have this blue border:

<Modal
        disableAutoFocus="true"
        aria-labelledby="transition-modal-title"
        aria-describedby="transition-modal-description"
        className={classes.modal}
        open={open}
        onClose={handleClose}
        closeAfterTransition
        BackdropComponent={Backdrop}
        BackdropProps={{
          timeout: 500,
        }}
      >

How i can remove this?

Add a class to modal, say egClass and set:

.egClass:focus {
    outline: none !important;
}
