Code snippet for changing redirect url

Hi John,

Could you provide us with a code snippet for functions.php to change the redirect url after switching? I would like to send all user to the homepage. I have seen https://github.com/johnbillion/user-switching/blob/0fbdead3deeb7b23f006f2a4e0ddce7f248f4d08/user-switching.php#L263-L289 but it is not clear to me how to create a snippet from that code. I also found this topic https://github.com/johnbillion/user-switching/pull/15/commits/43f47e64b7117dd57886b68aadc6f350c7ba07d0 with basically the same request.

I will appreciate your help!

With kind regards,

Sjors
