Missing schema name in swagger UI - addSchema API

[guerrap]

You have already researched for similar issues?

Yes

What are you trying to achieve, or the steps to reproduce?

I'm defining schemas with the addSchema API, but they are displayed without a name in the swagger UI. There's an autogenerated name def-0.
I'm using the openapi option in the register configuration.

app.addSchema({
    $id: "mySchema",
    type: "object",
    properties: {
        prop: { type: "string" },
    },
});

What was the result you received?

What did you expect?

To see the $ids of the defined schemas as names in the UI. In this case, I expected to see a mySchema in the schemes list.
Is there something I am missing? In the docs and in the issues I couldn't find anyone reporting this, maybe there's something I'm doing wrong.
