IoTHubDeviceClient_LL_UploadToBlob not availaible on Azure Sphere

How to use IoTHubDeviceClient_LL_UploadToBlob on Azure Sphere? This function is not present in any header file in following folder and compilation crashes on implicit declaration of this function.

C:\Program Files (x86)\Microsoft Azure Sphere SDK\Sysroots\8\usr\include\

It looks like Azure Sphere team bundles modified library. There are some additional functions like

IoTHubDeviceClient_LL_CreateWithAzureSphereFromDeviceAuth but lot of functions including IoTHubDeviceClient_LL_UploadToBlob are missing.

Is there possibility to upload file to Azure from Azure Sphere without need to do it fully manually?
