No way to archive batch proposals with multiple contracts

[KholdStare]

I have created a batch proposal that interacts with several contracts, and looks like this:

{
  proposalId: '1a8d8b0a-13c0-45e6-a4f2-bebb83d02f2f',
  contractId: 'mumbai-batch',
  createdAt: '2023-06-08T21:44:39.474Z',
  title: 'pause all contracts',
  type: 'batch',
  via: 'REDACTED',
  viaType: 'EOA',
  description: 'pause all contracts',
  metadata: {},
  contract: { name: 'batch', address: 'mumbai-batch', network: 'mumbai' },
  isActive: false,
  isArchived: true,
  steps: [
    [Object], [Object],
    [Object], [Object],
    [Object], [Object],
    [Object], [Object],
    [Object], [Object]
  ],
  contractIds: [
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED',
    'REDACTED'
  ],
  url: 'REDACTED'
}

I redacted some addresses. Note that contractId is mumbai-batch since it's actually several contracts in contractIds.

However the archive endpoint and the typescript function in the defender-admin-client only accept a single contract id. See https://docs.openzeppelin.com/defender/admin-api-reference#proposals-archive-endpoint

When I try to archive the proposal with the given mumbai-batch contractId I get this error:

  request: {
    path: '/admin/contracts/mumbai-batch/proposals/1a8d8b0a-13c0-45e6-a4f2-bebb83d02f2f/archived',
    method: 'PUT'
  },
  response: {
    status: 404,
    statusText: 'Not Found',
    data: { message: 'contract with id mumbai-batch not found.' }
  }

I feel like proposals are more general and should not live under the contracts path. it should be possible to refer to a proposal solely by its id.
