client_id           2
client_secret       TMcqRPVSh9IG9G9WgRh9k03sPSX13YwotEtzcKiR
grant_type          password

i got  "Welcome to admin Dashboard"

i can access using this type of Authorization.

but my doubt is how to get access token based on user role using this package and access role based resource like same the above process.

any one know solution for this process..

help me i hope yours. Thank you
