Whats the protocol for leaving a job during a pandemic?

So i have been increasingly undervalued at my current job, both financially and in the way i am being treated. Luckily I was able to secure a new role almost double the salary and I'm absolutely stoked on the people I will be working with. However I am not sure of the protocols really with leaving during this time and my current role is a contract position. Should I alert the head hunter who like "manages" my contract first? The boss in the role I'm in? should i do it via email?
