Microsoft Self Hosted Agent registered as Service instead of User Interactive While using Virtual Machine Scale Sets

Question

We created a Virtual Machine Scale Set then we created a new pool in the Azure DevOps interface and connected the VM Scale Set to Agent Pool.

When we are running a pipeline on this agent's pool then it throws the below error message:

TestComplete tests cannot be launched by an agent running as a service using TestComplete and TestExecute. Please configure the agent to run in interactive mode or assign this pipeline to an interactive agent (agents). Make sure to have an interactive user session open on the agent. Open the session manually or configure the agent to run with the auto-logon enabled to open the session automatically.

This means the agents are running as a service. I want to change these agents to Interactive agents. Would you please guide use to achieve this task.
