Codex integration not up to date on IntelliJ

The Codex integration plugin in AI assistant doesn't seem up to date, Like VSCode or even  Webstorm. I logged in via personal ChatGpt plus account on both, On Webstorm I have the all 4 thinking modes, low, medium, high and extra high thinking modes (reflects Codex plugin on VSCode). But on Intellij I only have medium and high, there is no extra high. How do we fix this?
