Add a new location to import nuget package

Hi Guys, I have just started to use github codespaces and in my existing repository I have some of my nuget packages deployed to a location in Azure Devops and not in nuget.org.

Currently I have a custom source for importing nuget packages in visual studio so I want to add this location in GitHub codespaces but can not seem to find any setting to do so, if any of you knows anything about this, please let me know.
