Using JSON objects in 'if' statements?

I'm making a site for my game server, and I'm trying to display user information using the Steam API.

$.getJSON('/steamapi', function(data) {

  document.getElementById("staff-inner").innerHTML = `${data.response.players.map(function(player) {

    return `

      <div class="player player-${player.steamid}">
      <div class="name">${player.personaname}</div>
      <div class="avatar"><img src="${player.avatarfull}"></div>
      <div class="role"></div>
      </div>

    `;
  }).join('')}`;

});

The above code is working fine. But, what I'm trying to do (and I assume this is the best way) is create an if statement that says if ${player.steamid} is my Steam ID, it prints 'Owner' in .role, and prints 'Moderator' if it's anything else. Seems like it would be simple enough, but everything I try leaves me with a blank page. I have no idea how or where I would write it in this context.
