Logging code make my code a bit ugly

Hi friends, Hope you're doing well, I'm working on complex project, I use CQRS with MediatR, in the Application layer, also I'm using Serilog ( Console, and File) for logging, and here the issue, the lines of code I wrote to achieve a logging it makes my code a bit a ugly ( in my opinion), because in the Commands and Queries I wrote a logging at the beginning and a logging at the end . The following is a Handle method of a Command :

    public override async Task<CreateCategoryCommandResult> Handle(CreateCategoryCommand request, CancellationToken cancellationToken)
    {
        try
        {
            Log.Information("CreateCategoryCommandHandler.Handle - Start Creating a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

// Some code goes here

            Log.Information("CreateCategoryCommandHandler.Handle - End Creating a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

            return result;
        }
        catch (Exception e)
        {
            var result = CreateCategoryCommandResult.Failed(e.Message);

            Log.Error(e, "CreateCategoryCommandHandler.Handle - Failed to create a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

            return result;
        }
    }

    public override async Task<CreateCategoryCommandResult> Handle(CreateCategoryCommand request, CancellationToken cancellationToken)
    {
        try
        {
            Log.Information("CreateCategoryCommandHandler.Handle - Start Creating a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

// Some code goes here

            Log.Information("CreateCategoryCommandHandler.Handle - End Creating a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

            return result;
        }
        catch (Exception e)
        {
            var result = CreateCategoryCommandResult.Failed(e.Message);

            Log.Error(e, "CreateCategoryCommandHandler.Handle - Failed to create a new category with name: {Name}, description: {Description}, and user id: {UserId}", request.Name, request.Description, request.UserId);

            return result;
        }
    }

Please I want you to share with me your experience about this, <3

Do you need to log all of that?

I don't know if logging statements inside of a handler is good idea in general, usually I've seen them wrapped around the sender in a custom dispatcher.
