Use my pi-top as an external monitor?

Is there any way to use my pi-top as an external monitor? I haven’t used it for about a year now, and I need a second screen for my current laptop for twitch streaming. Any ideas other than just using a website like spacedesk? I would like to have a wired connection if possible. Is there any way to just salvage the monitor?

Best,

Could I just use a htmi male to female cable from my computer, and plug it into the pitop hub 2.0? Could I use the power cord for the laptop to power the monitor?

I was curious if there was a software way to solve this, and I started Googling. Someone on the Raspberry Pi forums was able to hook up a pi to a second monitor and use TightVNC to get it working. That means you should be able to do the same thing with a pi-top.
