Programmatically signIn a user via service role

[etodanik]

I have a use case where I'm essentially implementing something similar to a token exchange flow (https://www.rfc-editor.org/rfc/rfc8693.html).

I'm essentially getting a valid token for a game launcher platform, then I create a user if doesn't exist on my Supabase app, and what I want to do is return my supabase token. Right now this seems needlessly complex (I think the only way to achieve this is via generating a custom OTP and immediately verifying it? Which seems clumsy).

What I really need is to be able to programmatically signIn() an arbitrary user using their email or phone via the service role, without having to do OTP or present any password.

Pinging this, because I'm actually doing it in production. It'd be super helpful if there was a way to do it without hacks.
