WebP Images Generator Osclass Plugin - Can't upload .webp images to listing

I'm using the WebP Images Generator Osclass Plugin v1.1.3 but I still can't upload .webp images to listings.

Isn't there a setting where we can allow the .webp-format to be uploaded?

I can't remember where I saw it.

Plugin has nothing to do with image upload supported extensions.

I understand. But where can I add .webp as an allowed upload extension?

It's not disabled because extension is missing in list
It's not integrated.

@Lucky,

change file oc-icludes/mimes.php to support webp .... remember every osclass update you need to change file...
