Hide 'Search for Jobs' button in the Career Site

Content

Once the candidate declines the Job Offer, the Thankyou message along with 'Search for Job' is displayed to the candidate. We have to remove/hide this button, so candidates will not have access to other jobs posted on the career site. 

Tried using below custom CSS code. However, the button and text highlighted appears in the career site

.offer-message__description
{
 display: none!important;
}
.offer-actions__button.offer-actions__button--primary
{
display: none!important;
}
