@abdou6666 I have 2 feedbacks:

1- The form component could be used elsewhere, so the entity id is not guaranteed to be passed in the URL.
2- When entity is fetched, you can check on the lookup strategy, if the array contains "keywords" then it can have synonyms. I'm afraid that passing the param "canHaveSynonyms" would/could introduce issues (Single source of truth)

Let me know what you think.
