Redirect specific user in Laravel after QR Code Scanned

I have a QR code generating link something like this https://example.com/6/4

Here:

=> 4 is ‘User ID‘

=> 6 is ‘Candidate ID‘

Means a user with only id 4 (after checking if he/she is logged in or not) should be redirect to a specific view with the details of candidate ID 6.

What i already have done:

1. Check if that user ID is currently logged in or not!

2. Candidate detail query with specific view.

I only need help how a specific user ID anywhere he is logged in can be redirected when this url is hit from controller?
