document-is-file
If the document is a file (as opposed to a folder).
{
"evaluator": "document-is-file"
}
Example
This block, taken from the Configuration docs, adds a custom-preview-in-website document action. If the user were looking at a file, this block would be included since it has a document-is-file evaluator.
{
"evaluator": "document-is-file",
"config": {
"document-actions": [{
"id": "custom-preview-in-website"
}]
}
}
