Issue description

Formatting JSON for hiding sub-elements under the "New" button in a SharePoint list.

Unable to hide "Clipchamp Video" under the "New" button. I was able to hide the below but not Climpchamp:
{
"key": "newWordDocument",
"hide": true
},
{
"key": "newExcelWorkbook",
"hide": true
},
{
"key": "newPowerPointPresentation",
"hide": true
},
{
"key": "newOneNoteNotebook",
"hide": true
},
{
"key": "newFormsForExcel",
"hide": true
},
{
"key": "newVisioDrawing",
"hide": true
},

Steps to reproduce - I have tried all variations:
Create a view and open format view panel
Use JSON to hide Export to Excel submenu from Export button
Insert this JSON
{
"commandBarProps": {
"commands": [
{
"key": "newClipchamp",
"hide": true
},{
"key": "newClipchampVideo",
"hide": true
},{
"key": "newClipChampVideo",
"hide": true
},{
"key": "newClipchampvideo",
"hide": true
},
]
}
}

What is the correct key to hide the "Clipchamp Video" sub menu?

Maybe not possible at the moment!? At least there's no key for this in the docs: https://learn.microsoft.com/en-us/sharepoint/dev/declarative-customization/view-commandbar-formatting#key
