Creating environments on the cloud terminal

I hope this is the right forum and not a question already asked, but I am working on an Android, and connect to here through the Anaconda Cloud. So, while here I can launch a terminal, and as expected this terminal has <> I also can create a new environment, and that is the core of my question:

How do I return to this new environment, where is it stored and how long will it stay available?

My idea is to install special packages on this new environment, ones I can install on <> because I got the warning that I don’t have write rights on this environment, which is logic, as it is the main working environment.

I hope I was clear, happy to edit the post if not clear, or elaborate on the idea .
