The correct feature is Cloud flow. Dynamics 365 Sales mobile app push notifications are created through Power Automate by using the Send push notification V2 action. Microsoft's Sales mobile documentation states that the Dynamics 365 Sales mobile app supports push notifications created with the Send push notification V2 action, where the mobile app is set to Sales, the target app is selected, recipients are defined, and the notification can open a specific table record when selected.

Power Automate documentation also describes the creation process as a notification from a flow: go to Power Automate, create an automated flow, choose a trigger such as Microsoft Dataverse, then add the Send push notification V2 action. That matches the requirement to configure several seller notifications for the Sales mobile app. Classic flow is not the correct answer because modern mobile notification automation should be implemented with Power Automate cloud flows, not legacy/classic workflow patterns. Plug-in is also wrong because plug-ins are server-side Dataverse extensions for custom business logic; they are not the standard no-code configuration mechanism for mobile push notifications.
