Step 1 of 4Open Plugins

The walkthrough uses the original ChatGPT web plugin captures. After connecting, open Codex in the desktop app and start a new task with ApexGenius. A ChatGPT web connection does not verify Codex access.

A public ApexGenius plugin listing is not verified. Use a plugin shared with you or one you created, subject to your account and workspace policy.

What Codex can do in Google Chat

4 operations. Read looks things up and changes nothing. Write changes Google Chat and runs only when that tool is enabled.

Read3 operations

Looks things up. Changes nothing.

Find and read

  • search_conversationsFind spaces, group chats and direct messages by name or by the people in them.
  • search_messagesSearch messages across your chats by words, sender, mentions or unread.
  • list_messagesRead the messages in one space, chat or thread, in order.

Write1 operation

Changes Google Chat. Runs only when enabled.

Send

  • send_messageSend a message to a space, chat or thread, with up to 10 mentions.

You choose what Codex can use

When you approve Codex, pick Full access, Read only, or Custom. Read only allows the Read operations and nothing else. Custom picks apps and tools one by one.

Limits in Google Chat

  • · The connected Google account decides which spaces and messages can be read. Messages only one person can see are left out.
  • · A sent message reaches people right away. ApexGenius cannot unsend it.
  • · Enabled writes run immediately. Turn a tool off to block calls.
  • · Disconnecting stops future access. It does not remove a message already sent.
