Resetting conda default channel after deletion in Conda environement - Anaconda

If I delete the default conda channel and would like to add it back again later, how do I do that? is there a URL link just like for conda-forge channel URL link that I just add (because I can't find one)? or writing "default" is just gonna work?

• I added conda-forge channel URL to my environment using Anaconda Navigator.
• I want to delete the default channel to test some things out.
• I want to be able to add the default channel back later.

Conda recognizes defaults as a special name. Any other non-URLs are interpreted as channels on Anaconda Cloud. E.g.,

• "conda-forge": https://anaconda.org/conda-forge
• "anaconda": https://anaconda.org/anaconda
• "bioconda": https://anaconda.org/bioconda

Unless you're using a local mirror or proxy, most users never need to use a URL.
