Meaning of "limits" and "appCreator" in JSON data of activity-log

They are always blank.
Please tell me what kind of content will be included.

appCreator will be either null, if the action was not created with an app token, or it will be an object with id, optionally a name string and optionally a icon object with a url string prop.

Please note that as for now appCreator.name is only set for Butler. appCreator.id is set for all applications. appCreator.icon is set if the dev configured it.

As for the ‘limits’, you should probably give more context. How and where you’re getting it exactly…
