it is now your task to specify the features of the new tool. Which role do you have
developer
product owner
designer
Where do you document the details of your idea? (or also, where can you have a look at when you want to learn more about it)
I create a product page in confluence where I formula the key requirements of my feature and other important details
I am creating a user story ticket in JIRA for that
I create a bug ticket in JIRA because the feature does not exist yet
I write an email to the Quality Assurance lead, Michael, to make sure he can document it
