Reset a custom reward's prompt?

[Omsad]

Hi,

How do you reset the prompt shown to a user for a custom reward. E.g if you do the following:

1. Create a custom reward with IsUserInputRequired = true and Prompt = "My test prompt" .
2. Then update the created custom reward to IsUserInputRequired = false and Prompt = "".

The prompt will remain on Twitch as "My test prompt" instead of being reset to blank. Is this the expected behaviour?
