Sending a RAM array instead of a file using storage.upload()

[Radistor]

Hello, everyone.
I'm trying to migrate from the previous version of the client (Firebase Arduino Client Library for ESP8266 and ESP32 4.4.14), which is already marked as deprecated, and I'm facing a seemingly simple problem - I don't see a direct replacement for sending a buffer from RAM to Firebase Storage, as it was easily to do before:
Firebase.Storage.upload(&fbdo, storage_bucket_id, fb->buf, fb->len, filepath, "image/jpeg");
Instead, in all overloaded versions of the upload procedure, the new version contains a file_config_data &file instance, which is not easy to create in RAM. Am I wrong and am I missing something?

Define the BlobConfig object globally.

Then set your image buffer pointer and its length with the object defined.

BlobConfig upload_data; // Global define

setup()
{
    upload_data,setBlob(fb->buf, fb->len);
    
    // Firebase Storage
    storage.upload(aClient, FirebaseStorage::Parent(STORAGE_BUCKET_ID, "filename.jpg"), getBlob(upload_data), "image/jpeg", asyncCB, "uploadTask");

    // Cloud Storage
    cstorage.upload(aClient, GoogleCloudStorage::Parent(STORAGE_BUCKET_ID, "filename.jpg"), getBlob(upload_data), "image/jpeg", asyncCB, "uploadTask");
}

Note that, fb->buf should be existed (not deleted or destroyed) while uploading.
