Hey, here's the solution

.sqs-block-button.button-block .sqs-block-button-element:hover {

  background: black !important;
  color: white !important;

}

If you just want to target the ones on this page, wrap the code in the page selector like this

#collection-61518c2b8e6b8d0a91c9825d {

.sqs-block-button.button-block .sqs-block-button-element:hover {

  background: black !important;
  color: white !important;

}
}
