`Microsoft.Extensions.Logging` and Serilog compatible timing library?

I'm currently using https://github.com/nblumhardt/serilog-timings to log how much time a given operation took. It was nice and all when I was using a static logger, but I wanted to switch to an injected ILogger instance. Problem is, SerilogTimings works on a Serilog.ILogger instance, not MEL.ILogger which feels kinda smelly to me. Is there any other library I could use with Serilog and MEL that would let me easily time whatever operations?

[SuppressMessage("Usage", "CA2254")]
public sealed class Operation(ILogger logger, string messageTemplate, params object[] args) : IDisposable
{
    private static readonly double StopwatchToTimeSpanTicks = Stopwatch.Frequency / 10_000_000.0;
    
    private readonly long _start = (long)(Stopwatch.GetTimestamp() / StopwatchToTimeSpanTicks);

    public void Dispose()
    {
        var elapsed = Stopwatch.GetElapsedTime(_start).TotalMilliseconds;
        var template = $"{messageTemplate} in {{Elapsed:0.0}}ms";
        object[] args1 = [..args, elapsed];
        logger.Log(LogLevel.Information, template, args1);
    }
}

You could also just use traces and start a new Activity. And you can log traces to serilog if you really want to with Serilog.Tracing
