Automatic Failover for Basic Availability Group

This will be my first project with Basic availability group so I thought would check before implementing . As per Microsoft documentation below it says we will need to have Software assurance for failover servers for disaster recovery / high availability. https://learn.microsoft.com/en-us/sql/sql-server/editions-and-components-of-sql-server-version-15?view=sql-server-ver15 Will greatly appreciate if someone can clarify on this as I will need to have the capabilities to do automatic / manual failover without the need to purchase software assurance
