I like the switch back to contextMenu. I originally switched to sheet because not all the info could fit in the menu. Not sure why I didn't think of adding a details button and sheet like you did...

One thing I'd like to request from you, then I can do a followup commit for the rest:
The new MessageInfoSheet doesn't include path-hash size and original send time. I think your PR came in before I added those to the old sheet. Please add them to your new detail sheet:

// after the hops row
if let hashSize = message.pathHashSizeIfKnown {
    Text(L10n.Chats.Chats.Message.Info.pathHash(hashSize))
}

// after the sent row
if message.timestampCorrected {
    Text(L10n.Chats.Chats.Message.Info.originalSendTime(
        message.wireSentDate.formatted(date: .abbreviated, time: .standard)))
}

Added those two fields.

Hi @0PandaDEV, just wanted to give you a heads up that I decided to revert the context menu and reimplement the sheet. The context menu was causing message drift issues that were proving difficult to fix due to the chat view being a flipped UIKit table (this was done because SwiftUI scroll view currently doesn't work well for chats). A lifted preview worked, but required so much extra code and workarounds for right-click on iPadOS/macOS that I decided to go back to the sheet. When it's possible to switch to only SwiftUI for the chat view with no bugs (such as bottom anchoring), I'll likely think about switching to a context menu again.
