Need help with Store-API CMS endpoint

Shopware 6 (English)

We are using a plugin which adds a downloads block to the page. The data returned only includes the media id and we need the media information to included.

We’re using this store-api endpoint:
/store-api/cms/{PAGE__UUID}

{
    "blocks": [
        {
            "versionId": "0fa91ce3e96a4bc2be4bd9ce752c3425",
            "type": "na15-downloadcenter",
            "slots": [
                {

                                    "createdAt": "2023-11-08T13:42:14.981+00:00",
                                    "updatedAt": null,
                                    "id": "018baf2b4117742d9d52e3f1563d2a32",
                                    "title": null,
                                    "apiAlias": "na15_file_category"
                                },
                                "priority": null,
                                "id": "018baf2b825f7b6b97931ea1cb41d409",
                                "title": null,
                                "mediaId": null,
                                "apiAlias": "na15_file"
                            }
                        },
                    },
                    "apiAlias": "cms_slot"
                }
            ],
        }
    ]
}

For the product endpoint I ended up using this in order to include media entity data:
store-api/product/{PRODUCT__UUID}

{
    "associations": {
        "na15_file": {
            "associations": {
                "translations": {
                    "associations": {
                        "media": {}
                    }
                }
            }
        }
    }
}

Is something like this possible for the CMS endpoint as well? Or is there a way using the store-api we can retrieve media information by id?
