Custom translation engine

This thread is resolved. Here is a description of the problem and solution.

Problem:
You are trying to use a custom translation engine, specifically an OpenAI compatible endpoint, to translate your site but are unsure if WPML supports this.
Solution:
We currently do not support the use of custom automatic translation engines with WPML. You must use one of the four integrated translation engines: DeepL, Google, Microsoft, or WPML AI. For more information on automatic translation with WPML, please visit our documentation: https://wpml.org/documentation/automatic-translation/

If this solution does not apply to your case, or if it seems outdated, we recommend opening a new support ticket. We also highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. For further assistance, please contact us through our support forum at https://wpml.org/forums/forum/english-support/.

robinV-30	Background of the issue: I am trying to use custom translation engines for my site, specifically an OpenAI compatible endpoint, to translate my site. Symptoms: There is no specific issue or error message mentioned. Questions: Do you have any documentation regarding the implementation of custom engines besides DeepL, Google, Microsoft, and WPML AI? If there is no documentation, could you provide the necessary hooks to set up a new engine?
