SendMagicLinkEmail puts RedirectTo option in incorrect part of request

[RedChops]

It seems like SendMagicLinkEmail appends RedirectTo to the POST body of the request, but it looks like the server expects it to be a query parameter. When a magic link is requested using this library using a redirect_to option, the magic link returned from the server ignores the option passed.

I spun up a Supabase instance here so I could dump the request data and used two client environments: a Flutter app which I know works, and a C# app which does not, both using the same API.

When requesting a magic link using the flutter library, it makes a request to the server like so:
POST /auth/v1/magiclink?redirect_to=com.example.example%3A%2F%2Flogin-callback%2F HTTP/1.1" 200 2 "-" "Dart/2.16 (dart:io)
with a POST body of:
{\x22email\x22:\x22email@example.com\x22}

Using this C# library, the request instead looks like this:
POST /auth/v1/magiclink HTTP/1.1" 429 91 "-" "Dalvik/2.1.0 (Linux; U; Android 12; sdk_gphone64_x86_64 Build/SPB5.210812.003)
with a POST body of:
{\x22email\x22:\x22email@example.com\x22,\x22redirect_to\x22:\x22com.example.example://login-callback/\x22}
