It is a great feeling to have an Instawork Partner invite you back or hire you full time to work after you complete a gig with them.
However, if work is ever agreed upon outside of the Instawork platform (i.e.: there isn't a gig scheduled through the Instawork app):
you will not be able to get paid by Instawork, and
you will not be covered by Instawork's insurance.
