So, in our data source we have a lot of data stored together with a map to determine parent and child hierarchy. The data is stored in 2 tables: [Event] and [Map_Events] [Event] consists ...

Source = Map_Events,

each Table.SelectColumns(_, {"parent_id", "child_id"})

Load the flattened hierarchy table along with the Event table into Power BI.
Ensure there are proper relationships between these tables. Relationships should be set based on id fields.
