Open files in the same window


I wanted to know if it was possible, when I click on a .ipynb file, that it opens in a new tab on an already existant jupyterlab window instead of opening a new window.

For now, I use a batch file to open my file with desktop in root dir like this:
start "" C:\JupyterLab\JupyterLab.exe C:\Users\Robert\Desktop %1

if you know how I could change that, it would be great!
