Word cloud/multi-poll query for groups

I'd like to build an activity in which I ask students to type in a few words or phrases in response to a question to get them reflecting. 

I'd then like to collate students responses across a group (updating in real time) and display them in a word cloud.

I’ve seen there are multi-polls and a WordCloud ‘game’ type H5P, and have had a play with them, but have 2 questions:

1. How do these H5P interactives display to students? – is it obvious where they have to enter their words? (from my ‘presenter’ perspective, it looks more like just the word cloud displaying)
2. Will this collate answers across all students in the class, and display it back to students in real time, or will students only see their own responses (and only me as presenter will get to see the whole group's responses)?
   

thanks for any advice
