Woocommerce toggle show/hide password

I searched this support forum and find many questions and answers regarding this. But all your answers were that by default woocommerce doesn’t allow any such option.

I tested my website and my account page with default wordpress theme (Twenty twenty one) and this works (I attached screenshot). But it is somehow disabled in your theme functionality.

Please give us instruction how can we re-enable this option because all users today prefer to have it.

Thanks
