VS Code autocomplete for ArcPy

What I had to do to get IntelliSense working with my arcpy project in VS Code:

1. In my project folder I created a new folder called .vscode

   

2. In this folder I created a file called settings.json, and added the following to the json file:

   {
       "python.pythonPath": "C:\\Program Files\\ArcGIS\\Pro\\bin\\Python\\envs\\arcgispro-py3\\python.exe"
   }
   

   This is the path to my arcpy python install location - if yours is in a different location then specify that path instead.

3. Now when I open that project folder, I can type arcpy. and then press Ctrl+Space two or three times and it'll pop up a message "Loading"

   

   I had to wait several seconds (it wasn't a quick load), then the IntelliSense works.

   

I did find I had to do the Ctrl+Space step and wait for the load every time I opened the project, but while it was open the IntelliSense works fine after initial load

With the help of Midavalo answer, I figured out how to set up autocomplete for my VS Code. In VS Code just go under File -> Preferences -> Settings and then within Settings go for Text Editor -> Suggestions -> Quick Suggestions and open settings.json(Edit in settings.json). Over there add the same line of code that Midavalo posted

{
"python.pythonPath": 'Path to your envrionment'
}

However, I think that my approach will set every python project environment to the one you pointed but there should be no problem to override this change on the 'select interpreter' option.
