Commands can be called with partial argument content. If any required properties are missing, the user will be queried. Extraneous properties will be ignored.
Example:
vscode.commands.executeCommand("apax-v3/apax/create", {
directory: vscode.workspace.workspaceFolders?.[0].uri,
project_name: "user-application"
});
In the above example, the template_name property is omitted, therefore the user will be prompted for the template name.
