Trouble importing Ajv using cdnjs.

I want to use Ajv on a webpage and I don't want to use a bundler.
So I'm trying to import Ajv from cdnjs, but I get the following error:
```
Uncaught SyntaxError: The requested module 'https://cdnjs.cloudflare.com/ajax/libs/ajv/8.11.0/ajv7.min.js' does not provide an export named 'default' (at validation.js:1:8)
```
It feels like I'm missing something so any help on how to fix this would be appreciated.
