-Create a bucket in Object Storage and upload the wallet there. Note the name of the bucket and the wallet object name.

-Your policy should look something like this:
-```
-Allow dynamic-group <dynamic-group-name> to read objects in compartment <compartment-name> where target.bucket.name='<bucket-name>'
-```
 
 If you choose to retrieve the wallet from Autonomous Database directly during the execution of the function, note the OCID of the Autonomous Database and create an IAM policy that allows the dynamic group to use the autonomous Database with the specific permission 'AUTONOMOUS_DATABASE_CONTENT_READ'.
