Find Artist and Create Cover Art

# Find existing Asset and create an Attachment
#
# Main function, establishes a connection to DataTrails using an App Registration then uses that
# to find existing Asset and create an attachment.
#
# Note: The purpose of DataTrails Jupyter Notebooks is to provide simplified examples that one can easily execute and digest.
# The DataTrails Python SDK is authored to work cleanly with more advanced coding techniques.
