TM API - TM object - tokenizerflags vs recognizer

Hello developer team,

we are preparing the migration of our TMs on Group Share 2020. We want to create TMs that are exactly set up like on the old server. For this, we export the TM properties and we import them on the new server.

In the list of properties of a TM, we have 2 similar objects: TokenizerFlags and Recognizers. In the user interface, we can see the recognizers (date, numbers, alphanumerics...) but we can't set any tokenizer flags. Can you explain what's the difference between tokenizerflags and recognizers is and how the tokenizerflags are set when a TM is created manually?

Thank you
