jQuery .hide() button when another button active

Question

I have a "Load More" button that has a class named .btn.btn-primary.ng-scope. When we have some items to show and class .btn.btn-primary.ng-scope.ng-hide when all units loaded.

My problem is that I have another button "Show All Available Units" with class .btn.btn-primary.custom. I need to show button "Show ALL Units" ONLY when button "Load More" has class .ng-hide

jQuery(document).ready(function() {
  if (jQuery('.btn.btn-primary.ng-hide')) {
    jQuery('.btn.btn-primary.custom').show();
  }
  
  if (jQuery('.btn.btn-primary.ng-show')) {
    jQuery('.btn.btn-primary.custom').hide();
  }
});
