I’m following this tree-view example: https://github.com/microsoft/vscode-extension-samples/blob/main/tree-view-sample/USAGE.md

"contributes": {
"commands": [
    {
        "command": "nodeDependencies.refreshEntry",
        "title": "Refresh",
        "icon": {
            "light": "resources/light/refresh.svg",
            "dark": "resources/dark/refresh.svg"
        }
    }
],
"menus": {
    "view/title": [
        {
            "command": "nodeDependencies.refreshEntry",
            "when": "view == nodeDependencies",
            "group": "navigation"
        }
    ]
}

}

I would like to add an extra condition to the when clause (when": "view == nodeDependencies"). For example, only show the fresh button if the file is a file with name ending in “.xs.ts”. I’m using resourceFilename and regex pattern to set such condition:

"contributes": {
"commands": [
    {
        "command": "nodeDependencies.refreshEntry",
        "title": "Refresh",
        "icon": {
            "light": "resources/light/refresh.svg",
            "dark": "resources/dark/refresh.svg"
        }
    }
],
"menus": {
    "view/title": [
        {
            "command": "nodeDependencies.refreshEntry",
            "when": "view == nodeDependencies && resourceFilename =~ /.*\.xs\.ts/",
            "group": "navigation"
        }
    ]
}

}

Although, a similar condition works for view/item/context and editor/title, it doesn’t work for view/title. If I add another clause besides the one checking the view’ name (view == nodeDependencies) the refresh button doesn’t show up.
