First of all make sure you have Fabric and Fabric API installed for 1.18.2

If you launch the game without OptiFine and only OptiFabric, it will show a message like this:-
This means you need OptiFine in the Mods folder as well
Get This version of OptiFine which I tested with and put it inside the mods folder alongside OptiFabric for 1.18.2
You can then launch the game and check video settings to see a Shaders button and OptiFine written on lower left corner.
