 - `tag`: The tag to uploaded into. If you want the current event's tag, use `${{ github.ref }}`
 - `overwrite`: If an asset with the same name already exists, overwrite it.
 
+
+Optional Arguments
+
+ - `draft`: The release will be marked as a draft if this is set
+ - `file_glob`: If set to true, the file argument can be a glob pattern (asset_name is ignored in this case)
