What is the expiry of property we set using d Properties.setProperty(key, value) method of Class PropertiesService

Question

I am unable to find what is the expiry of property we set using Properties.setProperty(key, value) method of Class PropertiesService. I know we can delete it using deleteProperty(key).

example: var userProperties = PropertiesService.getUserProperties(); userProperties.setProperty('userEmail', "user@xyz.com");

When the value of userEmail will be removed from the storage if we don't delete it using deleteProperty(key) method?

In the current state there does not appear to be an Expiration Time property within the Service Properties, this would need to be set manually. Something like this:

const EXPIRY_TIME_KEY = "expiryTime"
const HAS_ACCESS_KEY = "hasAcces"
const userProperties = PropertiesService.getUserProperties()

function isExpired() {
  const expProp = userProperties.getProperty(EXPIRY_TIME_KEY)
  const checkerTimer = (new Date().getTime() - expProp) / 1000
  /* 1 hour timer */
  if(checkerTimer > 3600){
    userProperties.setProperty(HAS_ACCESS_KEY, false)
  }
}

function grantAcces() {
  userProperties.setProperty(EXPIRY_TIME_KEY, new Date().getTime())
  userProperties.setProperty(HAS_ACCESS_KEY, true)
}
