https://github.com/gitcoinco/passport-sdk/blob/1b30f28575b1f6fe5a35fe400265775b4be15317/packages/types/src/index.d.ts#L122

Gitcoin Passport now supports additional providers like "Brightid" | "Github" (see https://github.com/gitcoinco/dPopp/blob/main/types/src/index.d.ts#L125)

We should also consider accepting any string for the passport-sdk PROVIDER_ID type, to allow other developers to easily use their own applications
