Need an iOS app to timeout or signout user after a certain period of inactivity

Hey guys,

I've been assigned a project at work to setup some iPad minis as Kiosks. I'm using Meraki MDM to do everything, but I can't seem to get the app that we're going to be using to timeout after a certain period of inactivity. Essentially, we are using an application that requires user to login with their own credentials, but the app doesn't sign them out after a certain period which won't work for us, because the iPad will be setup to be accessed by all employees.

So I need it to automatically sign out or refresh the app after a certain period of time of inactivity. Tried Kiosk mode from Meraki and the Guided Access from the Accessibility menu in Settings, but they don't sign out the app. Tried the Screen Time setting also, but this just locks out the app after a certain amount of time has been used. Doesn't help.

I'm not even sure if it's possible, but just wanted to reach out here and see if anyone had any ideas, or if I'd just have to reach out to the app developer and see if I'm missing a setting within the app.
