"replace_text_in_raw_data" function in pycelonis does nothing

I need to do quite a few mass changes across multiple dashboards and replace_text_in_raw_data was exactly what I wanted, but It doesn’t seem to replace anything.

For testing purposes I used simple saved formula:

replace_text_in_raw_data

Command I used in python:

analysis.replace_text_in_raw_data("replace_text_testing", "It worked")

but no matter what I do I dont see any changes.
