Is the "Generate Variables" the same as "Tools > Function"?

The community member is asking if the "Generate variables" option in the OpenAI block is an easier way to create a function under "Tools > function" in the OpenAI block. The comments suggest that this feature allows generating Typebot variables from an AI prompt, and that it is used in the High ticket lead follow-up template. However, there is no explicitly marked answer to the original question.
