ios – How to delete user only post

I am trying to delete my user post but I only want to allow my user to delete their post not the other users post. This is my user post the delete (trash) button is being displayed for the user .
My problem is the delete button is also being shown for the other users allowing me delete their post which is counterproductive. I don’t want to others users to see their delete button I only want the person who uploaded the image should see that button and be able to delete that post

How do I change this code for the delete button only to be shown for the user post and not the other users ?

@ObservedObject var viewModel: FeedCellViewModel
@State private var isFollowed = false
    @State private var height: CGFloat = 200

    private var user: Userss? {
        return viewModel.post.user
    }
    
    private var post: Post {
        return viewModel.post
    }

var body: some View {
 HStack(spacing: 16) {
 if isFollowed {
                            Button(action: {
                                Task { didLike ? try await viewModel.unlike() : try await viewModel.like() }
                            }, label: {
                                Image(systemName: didLike ? "heart.fill" : "heart")
                                    .resizable()
                                    .scaledToFill()
                                    .foregroundColor(didLike ? .red : Color.blue)
                                    .frame(width: 20, height: 20)
                                    .font(.system(size: 20))
                                    .padding(4)
                            })
                            
                            NavigationLink(destination: CommentView(post: post)) {
