pyscript not showing in developer tools -> actions

I installed the pyscript integration, added to my configuration.yaml file:
```
pyscript:
  allow_all_imports: true
  hass_is_global: true
```
I restarted Home Assistant, I see the integration in Settings -> integrations, and no errors in the log files.
But, when I go to Developer Tools -> Actions, pyscript is not there.

Did I miss a step?
