With the disclaimer that we haven't focused on this use case yet so there isn't an easy way to do it, here is one way to do it right now...

Make sure you have Python 3 installed on your computer.
Install the Microsoft Python and LEGO EV3 extensions in VS Code.
Create a new project in VS Code using the LEGO EV3 extension.
Open the main.py file to activate the Python extension in VS Code.
Open a terminal in VS Code and create a virtual environment in your project. (On Windows use py -3 instead of python3.)
```
python3 -m venv .venv
```
VS Code should ask you if you want to use the virtual environment that you just created. Answer yes. If it doesn't, select the virtual environment as the Python interpreter in the status bar (see Microsoft Python link above for screenshots).
Use the command palette in VS Code to open a new Python terminal (search for Python: Create Terminal command).

In the Python terminal run the following

python -m pip install --upgrade pip
pip install git+https://github.com/pybricks/pybricks-api@master

Code completion should be working already when you make this change.
