Replacement for logtiming

As of sunsetting of GA for app. It always recommend us to use firebase analytics. However, one feature that I have not found any alternative is logtiming. A log function that we could log duration of anything. Such as loading time of popup or average http response. Timing is useful in general

If we switch to firebase, the function itself is missing. So what is the best approach to replace those logtiming function in firebase analytics?
