I need to save appState in runtime, app page. I'm looking for any way to manipulate config.json in runtime (widget.tsx) like we do with props.onSettingChange in setting.tsx. Redux, mutableStateChange etc. does not work because settings will be saved permanently so other users can access. Basically I need to save into local file in exb environment.
Please do not suggest saving into redux or don't ask why I need these. I'm telling because I see those kind of empty replies/questions in all around community posts.

If you are not trying to alter things for all users, your best option would be to use localStorage or cookies on the user's browser.
