How to create this shape using only CSS?

I want to create this shape using CSS but cannot get the top right corner to work.
enter image description here

this is all the code that I have.

ul.rounded-tabs li {
display: inline-block;
background: #ccc;
margin: 0 40px;
padding: 0.625rem 2rem;
position: relative;
border-bottom-left-radius: 25px;
border-bottom-right-radius: 25px;
cursor: pointer;
}

ul.rounded-tabs li:after {
content: '';
height: 20px;
width: 20px;
background: #ccc;
position: absolute;
top: 0;
right: -20px;
z-index: 1;
}

ul.rounded-tabs li span:after {
content: '';
height: 40px;
width: 40px;
background:transparent;
position: absolute;
top: 0;
right: -40px;
z-index: 2;
border-radius: 50%;
}

    You need to use css :after Pseudo-element with box-shadow.

    ul.rounded-tabs li {
  display: inline-block;
  position: relative;
  margin: 0 40px;
  padding: 0.625rem 2rem;
  background: #ccc;
  border-radius: 25px 0 25px 25px;
  cursor: pointer;
}

ul.rounded-tabs li:after {
  content: '';
  height: 20px;
  width: 20px;
  background: transparent;
  position: absolute;
  top: 0;
  right: -20px;
  border-radius: 10px 0 10px 0;
  box-shadow: -10px 0 0 0 #ccc;
}
    <ul class="rounded-tabs">
  <li>List 1</li>
  <li>List 2</li>
</ul>

    You can also do this with clip-path and a path() shape instead, which I find a little more straight forward than border and shadow tricks (although YMMV as paths don’t reliably support percentage measurements and calc so this may be less flexible). Here’s a rough example:

    body {
  background: purple;
}

ul {
  margin: 0;
  padding: 0;
  display: flex; /* or display: grid */
}

li {
  display: block;
  position: relative;
  text-transform: uppercase;
  font-family: "Arial Rounded MT Bold";
  color: lightgreen;
  background: black;
  padding: 8px 16px;
  margin: 0 8px;
  border-radius: 18px;
}

li::after {
  content: '';
  position: absolute;
  top: 0;
  left: calc(100% - 16px);
  height: 18px;
  width: 24px;
  background: black;
  clip-path: path("M 0,0 L 24,0 C 24,0 16,0 16,18 Z");
}
    <ul>
  <li>One</li>
  <li>Two</li>
  <li>Three</li>
</ul>
