Looker Studio Report Access without username and password

[kr_manish88]

Hi Team,

Is there a way to embed looker studio reports without the need to enter username and password may be using some tokens?

I want to load the reports on a bigger screen via an external application in presentation mode for people to see. 

Kindly share step by step process to set it up if possible.

Note: Making the reports public is not an  option.
