Connecting to snowflake S3 Account

Hello Everyone, I am trying to configure snowflake s3 database account. After adding the snowflake account details & validating - Account validation is getting successful but the snap isn’t able to fetch the schema & tables list . Just wondering, the account configuration tab doesn’t have an option to mention the role , then how the snap get those details. Why doesn’t the snap not able to get the tables list. I can able login to the snowflake account & execute the queries so there is no issue at my account. Can someone please help
