Sync Voiceover to Bungalow Video

I have an MP4 of the latest Warrego Typhoon Proof Bungalow walkthrough and a separate 1-minute-22-second voice-only track that I will send you by email. Your task is simply to marry the two: slow the existing video just enough so its runtime matches the audio, then drop the voice track in so it begins right at the start.

No extra transitions, fades, or special effects are required—I want the visuals to remain unchanged apart from the subtle speed adjustment. Please deliver the finished piece in the same MP4 format and at the original resolution. A quick confirmation screenshot of the timeline with matching lengths would be helpful before you export the final file.
