pop up message to explain the meaning of each emoji.

I recently created a post (no reply - only ability to react) with emoji reactions. Emojis can be interpreted differently; for example, a thinking face might convey curiosity, interest but also concerns, or doubts.
Two hands together in prayer could be interpreted as “pray” but also “please”.  Could we implement a small popup message when hovering over emojis to briefly describe what each reaction represents? 
This way, we’ll ensure that everyone is clear on what each emoji represents and in turn, the data collected (and the reports we obtained) will be more meaningful. Just an idea to see what the community thinks about this?
