Unable to save plots from a Jupyter notebook in Visual Studio Code

I couldn't find any light on this topic.

After a clean restart in a new laptop I'm unable to download plots from a Jupyter notebook from Visual Studio Code.

According to the official docs and my past experiences with vscode this is as simple as click on the save icon of the output of the cell o double click on the plot and save from the emerging tab that opens. But, as you can see, I've lost that icon and double click does nothing See screenshot

I'd love to get back this feature.

Thx in advance!

My settings.json file has this lines:

"workbench.colorTheme": "Gruvbox Material Dark",
"python.defaultInterpreterPath": "/opt/anaconda3/envs/bin/python",
"workbench.startupEditor": "none",
"terminal.integrated.inheritEnv": false,
"notebook.cellToolbarLocation": {
    "default": "right",
    "jupyter-notebook": "right"
},    

"editor.rulers": [
    {
      "column": 80,
      "color": "#928E7C20"
    },
    120
],

"workbench.colorCustomizations": {
    "sideBar.background": "#242424",
    "list.hoverBackground": "#292828",
    "notebook.cellEditorBackground": "#3D3F41",
    "notebook.outputContainerBackgroundColor": "#282828",
},
