I cannot make breaking large words (links) in a word cloud app:

You can either use hyphens: auto; as Andrei Fedorov suggested:

.tags {
      display: flex;
      flex-wrap: wrap;
      justify-content: center;
      max-width: 60%;
      margin: auto;
      padding: 0;
      list-style: none;
      border: rgb(0, 0, 0) solid;
      hyphens: auto;          <--------
}
