Need HDMI output from Laptop and input into ATEM MultiView

Hi, I need assistance in a connection set up between:

ATEM CONSTELLATION 1 M/E to LAPTOP to PROJECTOR

Basically, whatever I show on my laptop via HDMI connected to the projector, I want that video signal channeled into the ATEM switcher.

How do I do that?

I was thinking to connect 2 HDMI cables into the laptop. But, I'm sure there's a more efficient way to do this.

May be you can use HDMI splitter (like this one https://a.aliexpress.com/_omL7y7f)? I'm using this for splitting ATEM Mini output signal for both display and big TV screen.

atem contelation HD 1 have 6 outputs .. U can send it where u want . If U need HDMI , then use SDI to HDMI mini converter ..

I have a splitter that works fine with a laptop, but not for the ATEM Mini Pro. Any ideas why that would be?
