How to find the Campaign instance name for JWT authentication adding on Campaign Classic?

Hi Experts, 

I am following this document : https://experienceleague.adobe.com/docs/campaign-classic/using/integrating-with-adobe-experience-cloud/experience-triggers/configuring-adobe-io.html?lang=en# 

to add the project credentials in Adobe Campaign (Like Step 2) with JWT authentication

.

In the lower step 4, there is this command  : 

nlserver config -instance:<instance name> -setimsjwtauth:Organization_Id/Client_Id/Technical_Account_ID/<Client_Secret>/<Base64_encoded_Private_Key>

• where can I find the <instance name> in the Campaign Console?

I identified one part, Campaign Classic Home > Monitoring > Monitoring Instance > Instance : dsscamp

Should this be the instance name to enter?

• And also following the same lower step 4, "Login via SSH to each container where the Adobe Campaign instance is installed and add the Project credentials in Adobe Campaign by running the following command as neolane user. This will insert the Technical Account credentials in the instance configuration file." , how can I run the command " as neolane user "?

Many thanks in advance,
