The self-hosted version vs Pro plan supported features

[JumanaNajdawi]

Hello,
We want to implement the self-hosted version of the TileDesk.
But I want to check the below:

1. Can we add our OpenAI account credentials instead of using TileDesk's already configured account.
   

2. Is the 'Code' node available in the self-hosted version?
   

These features are labeled for pro plan and the self-hosted version is the version with free plan features, so, can you confirm if these items are available for the self-hosted version or not?

Thank you
