HTML/CSS button expand to left with message-CodePudding

I want to create a button like this:

.button {
  background-color: #099;
  color: white;
  text-decoration: none;
  border-radius: 60px;
  height: 32px;
  display: inline-flex;
  align-items: center;
  overflow:hidden;
  width: auto;
  max-width: 32px; /** I'm animating max-width because width needs to be auto, and auto can't be animated **/
  -webkit-transition: max-width 0.5s;
  transition: max-width 0.5s;
}

.button:hover {
  max-width: 300px;
}

.icon {
  font-family: "Font Awesome 5 Free";
  font-size: 16px;
  margin-right: 15px;
  padding: 0px 8px;
  display: flex;
  align-items: center;
}

.text {
  white-space: nowrap;
  padding-right: 15px;
}

<a href="#" >
  <span ></span>
  <span >Hakuna Matata</span>
</a>

But I need message to appear on left from icon. So, message is invisible by default and when button hovered - the button expands to left and message appears.

Another issue: I want message to have different height, border and background from icon' circle.

How can I do that?

    flex-direction: row-reverse;
}

Wrap one more element to make it relative position and use right with absolute position to expand from the right to left.

.button {
    display: inline-block;
    direction: rtl;
    margin: 0 0 0 400px;/* just for see is it expand to left. you can remove this line. */
    position: relative;
}

.button > * {
    align-items: center;
    background-color: #099;
    border-radius: 60px;
    color: white;
    direction: ltr;
    display: inline-flex;
    justify-content: end;
    height: 32px;
    overflow: hidden;
    position: absolute;
    right: 0;
    width: auto;
    text-decoration: none;
    max-width: 32px;
    /** I'm animating max-width because width needs to be auto, and auto can't be animated **/
    -webkit-transition: max-width 0.5s;
    transition: max-width 0.5s;
}

.button > *:hover {
    max-width: 300px;
}

.icon {
    font-family: "Font Awesome 5 Free";
    font-size: 16px;
    margin-right: 0;
    padding: 0px 8px;
    display: flex;
    align-items: center;
}

.text {
    white-space: nowrap;
    margin-left: 15px;
    padding-right: 15px;
}

<span >
    <a href="#">
        <span >Hakuna Matata</span>
        <span ></span>
    </a>
</span>

However, I don't understand your "message to have different height, border and background from icon' circle". If it is different height how can it be full rounded circle (it will becomes oval).
