Hello @pudnik26354 , welcome to the dbt community!
Overall, see this link first.
Specific notes on your steps:
It should be in the form of: my-account-id.my-region.my-cloud-provider for example ab138543.east-us-2.azure or zo234532.east-us-2.aws
the warehouse is not “Snowflake”, it is the name of the Virtual Warehouse within snowflake.
You can, but I would use a different role. See here and here
