Place Custom Checkbox Icon to right of label Bootstrap 4

I have tried everything but I can't place checkbox right to the label. I could move the checkbox to the right of label, if it is general type of checkbox. But I could not do the same with custom-checkbox type.

            <div class="custom-control custom-checkbox mb-3">
              <input type="checkbox" class="custom-control-input" id="customCheck" name="example1">
              <label class="custom-control-label" for="customCheck">Label</label>
            </div>
