Aaaaaah,

I just updated

'linkedin' => [
'client_id' => env('LINKEDIN_CLIENT_ID'),
'client_secret' => env('LINKEDIN_CLIENT_SECRET'),
'redirect' => env('LINKEDIN_REDIRECT'),
],

to

'linkedin-openid' => [
'client_id' => env('LINKEDIN_CLIENT_ID'),
'client_secret' => env('LINKEDIN_CLIENT_SECRET'),
'redirect' => env('LINKEDIN_REDIRECT'),
],
and its working.
