Seeing my viewers while presenting a powerpoint and them seeing me

Hi all, 

I am setting up a values based coaching tool for children and young people, and the training I am giving for this means I need to see my viewers and for them to see me while I present my powerpoint slides. 

Is there a way of doing this? 

I wonder if it is because I am currently using a school laptop until I do this full time, and the permissions may not grant me the full range of potential zoom video presentation options.

If so, do I need to get my own lap top and start afresh?

Thanks, 

Heather
