Redirecting from one URL to another within the same domain

Hi,

I'm trying to test redirects and I've been going through the rewrite documentation but not able to wrap my head around it. I wanted to redirect this URL: https://classbproject.com/contact to this URL: https://classbproject.com/category/guides/. I wrapped my rewrite within a location block but that does not work. What am I missing?

My server config is as shown below:

server {
## Your website name goes here.
server_name classbproject.com;
## Your only path reference.
root /var/www/classbproject;
## This should be in your http block and if it is, it's not needed here.
index index.php index.html index.htm;

error_log /var/log/classbproject_error_log;

location = /favicon.ico {
log_not_found off;
access_log off;
}

location = /robots.txt {
allow all;
log_not_found off;
access_log off;
}

location / {
# This is cool because no php is touched for static content.
# include the "?$args" part so non-default permalinks doesn't break when using query string
try_files $uri $uri/ /index.php?$args;
}

location /contact/ {
rewrite \/contact\/ \/category\/guides\/ last;
}

location ~ \.php$ {
include snippets/fastcgi-php.conf;
fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
}

location ~* \.(js|css|png|jpg|jpeg|gif|ico)$ {
expires 1d;
log_not_found off;
}

location ~ /\.ht {
deny all;
}
