Zip folder without including path to folder and require only one argument

Zip folder without including path to folder and require only one argument

I'm trying to make a zip function that'll do all the steps I typically do
when zipping a file or folder. Say my current directory is ~, and I want
to zip a folder named Folder1, whose file path is ~/Folder2/Folder1.
Issuing
cd ~/Folder2 && zip -r Folder1 Folder1 && cd -
does exactly what I want. Namely, it zips so that the output Folder1.zip
does not contain folders that lead up to the folder I'm zipping (namely,
/home/user/Folder2), it zips recursively, and it takes in the first
argument of zip with the exact name as the file or folder I'm zipping
(Folder1.zip).
So I want to make a function in my .zshrc something akin to
coolerzip() { cd /path/to/file && zip -r file file && cd - }
where it need only take in one argument, which in this case, it will be
~/Folder2/Folder1. Then Folder1 will be the name for both files in
coolerzip, and I will cd right into ~/Folder2 so Folder1 lies in my
current directory before zipping. Is there any way I can achieve this so
that coolerzip only requires one argument rather than three?
