how to get linked to entry data?

[phpstudyone]

I expect to retrieve all data linked to this entry. I used the following code:

const sdk = useSDK();
const entryId = sdk.entry.getSys().id;

sdk.cma.entry.references({ entryId: entryId, include: 10 }).then(a=>{
    console.log(a, 3343434)
})

But it seems that the returned data is the entry itself, rather than the data that references this entry. What did I miss?

To get the data linked to the entry, it seems that you can only call preview-contentful-api. But the cma in useSDK uses the manage-contentful api. How do I use useSDK to get this content?
