Sceptre C35 vesa mount

Hey! So I’m trying to get a new desk but the stand I have for my monitor is WAY too big! I wanted to get a mount for it but I don’t have my Vesa plate that came with it. To make things even worse they discontinued my monitor and now I’m completely stuck with no options. I thought I’d ask here before I give up hope.

Here’s the link to the mount I need but can’t get if that helps.
