Share to company page from not admin users

[TAGHREEDAA]

I'm using your package [Laravel-Linkedin by mauri870 for Laravel 5],

My case is that I want to share posts to Linkedin company page automatically.
I face a problem that the users of my website aren't admins in the company page so they can't post to it.

I wanna ask how can I make it?
How can not admins publish on the company page?

if not How can I put the email and the password of the admin within my code and force him to login automatically then share to the company page after that logout the admin account from code.
