If you are android, there is an app called Shelter that lets you create customized contained work profile inside which apps can be killed completely until you enable work profile again. This would usually be enabled by certain official app by your employer’s IT policy, such as MS’s Company Policy, so you don’t normally have control over what app to put in the profile, but with Shelter you can pick and choose any app into the work profile freely. If you have other apps you don’t trust, you can also use it to contain them too
