Currently, I can see like this:

But, need to add a category into that.

Thanks you in advance!

Answer: 
Could it be you've used PWA studio version 8?

If so this does not support Magento 2.3 according to <https://magento.github.io/pwa-studio/technologies/magento-compatibility/>

Although if this was the case you should have been informed during installation:

> 
> Since 2.1.0, PWA Studio includes a query validation step during the build process. This step reports on any GraphQL incompatibility it encounters.

Developers have two options for solving compatibility issues:

* Upgrade or downgrade the PWA Studio version to match the Magento 2 backend version
* Upgrade or downgrade the backend Magento 2 version to match the PWA Studio version
backend url needs to be https, please try that
