My ideas to gain more WGLF tokens
Flashlight saves = 2 tokens
Pallet saves = 2 tokens
Head on saves = 2 tokens
Safe hook rescue = 1 token
Unlocking the hatch and escaping with X teammates = X tokens, for example escaping with 3 teammates using the hatch you unlocked with your key gets you 3 tokens.
Unhooking a survivor who ends up escaping the trial = 1 token.
Blinding the killer while someone’s getting chased = 1 token

It would be impossible to gain tokens unlocking the hatch, as doing so forces you down the hatch first. You've already left the trial at that point.
They've already announced that they're adding new ways to gain tokens here: https://forum.deadbydaylight.com/en/discussion/194208/developer-update-september-2020#latest ; but I don't see it explicitly specified how.
I'm not sure what the devs did but WGLF already gave you tokens for saving your team by blinding and and pallet stunning... as for the hatch thing you're right it's impossible right now, but maybe the devs can pull something off for this to work, although i doubt they'll add anything from what i said but hey one can dream xd
