No procedure with the name `gds.alpha.collapsePath.mutate` in training module

During the training Introduction to Neo4j Graph Data Science

and for the specific lessor https://graphacademy.neo4j.com/courses/gds-product-introduction/2-graph-management/4-cypher-projection/ getting error as "There is no procedure with the name `gds.alpha.collapsePath.mutate` registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed."

On executing the following in the sandbox I am getting the error

````CALL gds.alpha.collapsePath.mutate('proj-native',{
relationshipTypes: ['ACTED_IN', 'HAS_ACTOR'],
allowSelfLoops: false,
mutateRelationshipType: 'ACTED_WITH'
});

Change alpha to beta. You will, however, run into a new issue when you execute the next snip of code. This I have not figured out yet.
