Urgent Help - want to download MacOS Monterary

Context: I'm using a mid 2014 MacBook Pro and I want to download macOs Monterary 12.7

But the popup notification tells me: "The update cannot be installed on this computer"

I really need to update to macos Monterary because I cant access most of the applications on my laptop, im just stuck at macos Big sur 11.7.10 for now

I'm also not knowledgeable about these tech stuff so please be forgiving
