Authorization profile without account

Hi,

i’m using the plugin without adding account and i want to display the instagram (for example: leomessi) account without entering a password.

I get this error “Instagram requires authorization to view a user profile. Use autorized account in widget settings”

How should i configure my instagram to give permissions without introduce account in the plugin?

and other question, ¿What is the API URL? My hosting blocks external connections

Thanks you
