Change Text in Custom Form Button

Add this code to 10-member Page Header

<style>
  .form-button-wrapper:after {
    content: "Next Step";
    background: #b94941;
    font-family: calluna-sans !important;
    font-weight: 700;
    text-transform: uppercase;
    color: white;
    padding: 0.5em 2.5em;
    border-radius: 300px;
    position: absolute;
    left: 0;
    min-width: 125px;
    pointer-events: none;
    text-align: center;
}
.form-button-wrapper {
    position: relative;
}
</style>

Because CSS can't rename text, so my idea is create new button then move it overlap current button
