Path length in the when querying a propery graph

SQL Help

I have a query as following:

select *
from GRAPH_TABLE(
match (c1 is customer) - [e is relationship]{1,10} -> (c2 is customer)
where c1.address_id = c2.address_id
columns (c1.name, c2.name)

How do I get the path length of the e?

Thanks,
Saqib
