I can't get to "Synonym" on Choice block

I’m a brand new user with no coding experience and am just trying to follow the example in your YouTube video Vol. 1. In that video you bring out the Choice block and type in the “answer” to “What is your favorite color?”. After you type “red”, you hover the cursor and then a “window” appears titled “Synonym”. How do you get that to appear? I can’t seem to find it right now and then the exercise “falls apart”. THank you for your consideration

That tutorial is old. Choice Block and Interaction Block has been merged as New Choice Block. New Choice Block is almost same as old Interaction Block. (so confusing…)

Also, some new features has been added to New Choice Block.

There are many updates so fast, but documents and tuttorials has fallen behind…
