Powershell - Upload to an Azure blob container

I have an Azure storage account with Blob containers and folders (also named containers?) within these blob containers. I have an Account Name and Account Key to access it and I can upload files using Microsoft Azure Storage Explorer. I have been searching for a simple script to upload files to a specific blob container but I have been able to find one. Uninstallig the RM-modules and installing the AZ-modules was already a challenge. The examples all seem to be very complicated (security is not an issue for this project) and I just cannot get them to work and I am newby to the subject.

Can anyone share a simple line of powershell script with me to do this?

I tried to upload files to a specific blob container by using below PowerShell script and got the result successfully:

Connect-AzAccount

$ctx = New-AzStorageContext 
-StorageAccountName 'YourStorageAccountName' 
-StorageAccountKey 'YourStorageAccountKey' -Protocol Https

Set-AzStorageBlobContent 
-File "C:\Users\Downloads\YourFileName" `  //Your file path
-Container YourContainerName 
-Blob "YourFileName" `  
-Context $ctx

The file got uploaded to the blob container successfully like below:

To confirm the above, check in the Portal whether the file is uploaded or not like below:

Please note that, to run the above script you need Azure modules like Az.Accounts and Az.Storage modules. You can refer this MsDoc to install the same.
