Unable to import and run Node-RED Dashboard 2.0 examples on CentOS server

### Description

Hello,

I am very interested in Node-RED Dashboard 2.0 and would love to explore it in depth by studying the provided examples. I followed the setup instructions from the repository to install the necessary packages on my CentOS cloud server, but I'm having trouble importing and running the example flows in Node-RED.

Here’s what I have done so far:

Cloned the repository on my CentOS cloud server.
Ran npm install successfully in the project directory.
Opened Node-RED in my web interface, but I couldn’t locate or import the example flows (such as flows.json).
I would be grateful if you could guide me on the correct steps to import and run these example flows in Node-RED, specifically in the Dashboard 2.0 environment.

Any assistance would be greatly appreciated as I’m eager to learn more about Node-RED Dashboard 2.0 through these examples.

Thank you for your time and help!
Best regards.
