In order to connect on-premises version of Azure DevOps, we'll need three pieces of information:
The names of Organizations
in Azure DevOps you want to be processed via Hatica
A personal access token
created in your Azure DevOps
Here's official documentation Azure DevOps on how to create Personal access token: https://learn.microsoft.com/en-us/azure/devops/organizations/accounts/use-personal-access-tokens-to-authenticate?view=azure-devops&tabs=Windows#create-a-pat
Here are the list of permissions required by Hatica via the personal access token:
'vso.code' (Code Read)
'vso.project' (Project And Team Read)
vso.profile' (User Profile Read)
'vso.build' (Build Read)
'vso.graph' (Graph Read)
