Updates to Snomed code notes for Reasonable adjustments appear with history

Hi,

I used ‘Create patient flag’ api endpoint to create reasonable adjustment flags with a few snomed codes. This created the record successfully. When I tried to amend the notes for a particular snomed code, it does save it successfully, but when I look into the test data portal in INT environment against the test nhs number, it is saved as,

ohggjhk

. ADDITIONAL NOTE added by Test user:

. Obviously, this is what is fetched by the Get patient flag endpoint as extension. Given there is no separate endpoint for updating, could some one help with getting the last updated text for the snomed codes to get it displayed in the front end correctly?
