How to Run or Deploy Code in Web IDE?

Dear Support,

I managed to create my Project using Native Kotlin Template and at the same time, uploaded .kt files into the SRC folder. These .kt files were downloaded from Github Repository Open Source (but imported as Gitlab and have been set to Private).

The .kt files I’ve open under Repository/Files - I select the .kt file and “Open in Web IDE”, which I did but how to run or deploy the .kt code? Is this the same as I used on my own VSCode? Is there a Terminal for me to download the .kt files and then Run the file?

Do you have the tutorial for my situation above?

Looking forward to your response - Thank you.
