I think the first `createActivity(...)` example is incorrect. The API mentions the following: * https://develop.kde.org/docs/plasma/scripting/api/ * https://invent.kde.org/plasma/plasma-workspace/blob/master/shell/scripting/scriptengine_v1.cpp#L223 * `JSValue ScriptEngine::V1::createActivity(const QJSValue &nameParam, const QString &pluginParam)` There's likely a few other undocumented changes since: * Plasma4 => Plasma5 * Port Plasma Desktop Scripting to QJSEngine https://invent.kde.org/plasma/plasma-workspace/-/commit/033ad5ca60b3d4250a4f354fa38fc60f7d97c78b Misc: ```md [`createActivity(name, plugin)`](https://invent.kde.org/plasma/plasma-workspace/blob/master/shell/scripting/scriptengine_v1.cpp#L223) ```
