Centre Recaptcha box

Good evening,

I used the following code from the WPForms site to centre the submit boxes on my forms:

/* This styles the submit button */
.wpf-center .wpforms-submit-container  {
    display: inline-block;
    text-align: center;
    width: 100% !important;
}

The codes works, however, I am struggling to find a way to centre the reCaptcha box as well. I changed the above code to:

.wpf-center .wpforms-recaptcha-container  {
    display: inline-block;
    text-align: center;
    width: 100% !important;
}

but this didnt work.

Any help is appreciated.
