WebFormAPI missing inProgress Tag

When paging for a response on an instance ID well a user is working on the form, there is only INITATED and SUBMITTED, Why isn’t there a way to see if they are filling in the form under INPROGRESS. So we can see if the user left mid form.

data: {
    id: '',
    clientUserId: 'guest_user',
    formId: '',
    accountId: '',
    tags: [],
    status: 'INITIATED',
    instanceMetadata: {
      expirationDateTime: '2026-03-29T08:24:26.078Z',
      createdDateTime: '2025-02-05T16:24:26.078Z',
      createdBy: [Object],
      lastModifiedDateTime: '2025-02-05T16:24:26.078Z',
      lastModifiedBy: [Object]
    },
    envelopes: [],
    formValues: {
      Language_Difficulty: [],
      Legal_Guardian_Emergency_Contact: [],
      Primary_Insurance_Coverage: [],
      Secondary_Insurance_Coverage: [],
      Contact_Preference: []
    }
  }
}
