> the flow the magic link is part of is one you initiate
There's nothing stopping anyone else from initiating the flow assuming the common implementation where only an email is required to initiate sending the link.
Here is the link you requested from ‘Android Device’ in ‘Belarus’ - click here to sign in and allow that device to access your account - only click this if you requested this email
You don’t click the link if you didn’t request it.
The phisher will be on the phone with their victim, pretending to be a support agent for the business. They will say, "Yes click the link, that's how you verify with us."
