New Parameter Examples

Initially Hidden Widget (Requires Custom Buttons)

Important: When using initiallyHidden: true, you must provide your own show/hide controls.

<!-- Your custom buttons -->
<button id="show-chat-btn" class="btn btn-primary">💬 Get Help</button>
<button id="hide-chat-btn" class="btn btn-secondary" style="display: none;">✖️ Close Chat</button>

<script>
  window.eptAIConfig = {
    accessToken: 'your-token',
    initiallyHidden: true,  // Widget starts hidden - YOU MUST provide show/hide buttons
    botName: 'Support Bot'
  };

  // Required: Add show/hide button handlers
  document.getElementById('show-chat-btn').onclick = function() {
    window.eptAIConfig.show();
    this.style.display = 'none';
    document.getElementById('hide-chat-btn').style.display = 'inline-block';
  };

  document.getElementById('hide-chat-btn').onclick = function() {
    window.eptAIConfig.hide();
    this.style.display = 'none';
    document.getElementById('show-chat-btn').style.display = 'inline-block';
  };
</script>

⚠️ Important: If you set initiallyHidden: true without providing show/hide controls, users will have no way to access the chat widget!
