body language - pointing out key elements on the slide

Hi, I have a question regarding to body language.

When I log onto the Online Practical Exam site, doing self evaluation, I notice the slides come up on the right hand side and the video on the left.
Hence when I need to point on my slide, my hand actually needs to point to left, the reverse side, so on the screen I see my mirror image to point to the right, to the slides.

Can I double check whatever I see on my screen is also how the audience/marker will see it?

Thanks
