Basic Node and Express - Use the .env File

I am trying to locate the .env file in the project I’m working on for this challenge. But, this file is nowhere to be found.
I’ve tried to work on Glitch and locally using vscode, but in vain.
Can someone help how to locate this file in my project? Can I create one manually?

Basic Node and Express - Use the .env File

Link to the challenge:

You can always manually create one, but if you use the link provided in the introduction section of these challenges, it will create all the files automatically (including a .env file), which is typically standard in all Glitch projects. Would you mind posting a link to your Glitch project, so I can check something?

Sure,
Here is the link for the project

That is odd about the missing .env file. Anyway, you can still create one manually and work through the challenges.

Thanks.
So, how do I create one manually on Glitch? Any hint?

I’ve created a .env file manually.
Thanks for this tip.
