Link to guide is missing

I’m working on a plugin to add support for WPGraphQL with ACF. When I go to the ACF field group and select a specific field, in the GraphQL tab, I see the following message:

Not supported in the GraphQL Schema
The "my-plugin" Field Type is not set up to map to the GraphQL Schema. If you want to query this field type in the Schema, visit our guide for?adding GraphQL support for additional ACF field types.

Here’s the link to the screenshot.

When I click on the adding GraphQL support for additional ACF field types it redirects me to the current page that I’m on. It seems that the guide has not been linked correct. I tried to Google but nothing much came up.

Request if you can please share the link to the guide here.

Thanks
