What is a requirement for sharing button flows?

To share button flows in Power Automate, the requirement is that the account must have access to Power Automate. This means the user needs to have the necessary licensing and permissions associated with the Power Automate service, allowing them to manage and create flows. Access to Power Automate ensures that the user can fully utilize the features and functionalities involved with creating and sharing flows, including button flows, which are interactive flows triggered by a user.

While the other options list roles that may possess various levels of access and administrative capabilities within environments like Dynamics 365 or Dataverse, they are not specifically necessary just for sharing button flows. Therefore, ensuring that the account has access to Power Automate is the essential prerequisite for sharing any type of flow, including button flows.
