Proposal get Response transaction data type definition

Using Typescript to create a proposal with Defender SDK node module. When implementing client.proposal.get(proposalId) to access transaction result there appears to be no transaction property on the ProposalResponseWithUrl type result.

:laptop: Environment
@openzeppelin/defender-sdk-proposal-client

:memo:Details
According to the documentation for the API/SDK the response for the proposal get should have a transaction property at the top level.

However, there is an error during compilation or when using an IDE with Intellisense:
Property 'transaction' does not exist on type 'ProposalResponseWithUrl'.ts(2339)

Following the type definition links into the OZ Defender node module there doesn't appear to be a transaction property

:1234: Code to reproduce

const result = await this.client.proposal.get(proposalId).transaction;
