How to open in Arduino IDE

[mogerken]

Hello, sorry if this is a dumb question, but I want to build the same project and found this code, but I can't figure out how to open it in the Arduino IDE without an .ino file. Do I have to create one by my self? Thank you!

Okay I figured out I needed Visual Studio Code with the platformio add-on but when I am trying to build it I get this error message:

Does anybody know how I can solve this?

I tried to rebuild the program but failed as well. Unfotunately there have been changes in the core library preventing using libraries like wifi manager. This is a fundamental issue which I haven't found a solution yet. As I am too busys whith other things, I need to approach this in a few months again.
