How to add dynamic slugs in .htaccess?-CodePudding

I am currently making a URL shortener site where I will be able to shorten links and then get the shortened URL and its unique id stored on the database. To access the shortened URL, I planned to add a slug to the URL making my URL look like this:

mysite.com/randomUrlId

But when I add a slug to my page (hosted here), it shows an error. I am very sure this can be done using the .htaccess file but I am not sure about how to approach it.

How can we add dynamic slugs?

This is the .htaccess file which I got by default:

# PHPVersion
#="php74"
AddHandler x-httpd-php74 .php
#-PHPVersion

# OptionsIndexing
#="1"
Options  Indexes
IndexOptions  FancyIndexing
#-OptionsIndexing

I got it. It was more like a hacky solution but what I did is I added my main index.html file to 404 error and now it works perfect. This is the line I added:

ErrorDocument 404 /index.html
