You should try using pyspark in all of your locations to verify with

df = spark.sql("select * from <catalog.schema.table>")
df.display()

Do this after you make your managed table in your desired external location path ofcourse.

spark.sql("create schema if not exists <schema name> managed location <external location url path>")
spark.sql("create table if not exists <schema name>.<table name> managed location <external location url path>")
