when #4128 gets merged I would also like to take this up as it is related to it, afaik we just need to make the options take the exporter types, also would like to know if some tests we gonna be writing regarding this ?

@wasup-yash

Yeah we pretty much want to use a Union of these types instead of the Python any. It will definitely be good to add some tests for this (pass in the various valid/invalid types to try to create a LogRecord).

@Ali-Alnosairi

As @xrmx has mentioned, please choose one issue to work on and open a PR accordingly instead of working on multiple different issues.
