VS Code debugpy hiding special and function variables via variablePresentation in launch.json does not work

Question

Other threads have suggested editing the launch.json debugpy configuration to edit the way cluttering variables are presented by adding variablePresentation:

{
    "configurations": [
        
        {
            "name": "Python: Current File",
            "type": "python",
            "request": "launch",
            "program": "${file}",
            "console": "integratedTerminal",
            "justMyCode": true,
            "variablePresentation": {
                "function": "hide",
                "special": "hide",
            }

        }
    ]
}

This was suggested here: How can I disable/hide the grouping of variables in vscode-python

However, this produces no effect. This makes it somewhat cumbersome when working on larger projects. Running:

debugpy version: 1.6.6 OS and version: Windows 10 Enterprise, version 21H2 Python version : 3.9.16, conda distribution VS Code, version: 1.76.1 (user setup)

Just wanted a sanity check to see if there is something obviously wrong :)

Tried to debug a currently active Python file. Expected cluttering variables to be not displayed. This did not happen - config edit resulted in no change from default behavious.
