How to implement Throttling Backoff

Question

Hi, I'm trying to implement an additional backoff function to handle this error, how do I handle exceptions when writing code that applies labels using the MIP SDK with C#? Unfortunately, it takes too many requests to recreate the throttling limit on purpose, and since it's not an HTTP request, I can't directly handle the 429 status exception. How does the method respond when the throttling limit is exceeded. For example, CommitAsync or CreateFileHandlerAsync
