Cannot start example

Trying to run a simple example to connect to AZ blob storage:

FROM docker.elastic.co/logstash/logstash:7.6.1                                                                                         

RUN logstash-plugin install logstash-input-azureblob                                                                                   
    
ADD azblob.yml /usr/share/logstash/pipeline/

input
{
    azureblob
    {
        storage_account_name => "mystorageaccount"
        storage_access_key => "VGhpcyBpcyBhIGZha2Uga2V5Lg=="
        container => "mycontainer"
    }
}

Hi Maczikasz,
I am glad to support you, can you let me know what do you try to do this example?
I am not sure what are you doing and your steps
