AshAuthentication custom strategy UI

I am trying to implement a custom strategy that verifies the user login with some custom rules, but after following this documentation i am stuck on where to implement the UI (https://hexdocs.pm/ash_authentication/custom-strategy.html) Is there any demo project that can serve as a reference for this? Do i just use UI Overrides? (https://hexdocs.pm/ash_authentication_phoenix/ui-overrides.html)

got busy suddenly but will try to look at the source code sometime, i saw there was an ash_authentication_firebase dep but it seems to use the same UI as the other OAuth2 strategies so there is no ui I tried to duplicate the Password Strategy from the source code hoping it would use the same for but nothing shows up i assume because it is linked to the original strategy struct, so will just try to make a new live view for the new custom strategy but am getting:

You can use the "struct.field" syntax to access struct fields. You can also use Access.key!/1 to access struct fields dynamically inside get_in/put_in/update_in)

tried to follow this post https://elixirforum.com/t/customizing-ash-authentication-for-dummies-like-me/66206 so i have:

#on mount
    api = AshAuthentication.Info.authentication_domain!(strategy.resource)
    subject_name = AshAuthentication.Info.authentication_subject_name!(strategy.resource)

    AshPhoenix.Form.for_action(strategy.resource, strategy.resettable.request_password_reset_action_name,
      api: api,
      as: to_string(subject_name),
      context: Ash.Helpers.deep_merge_maps(%{}, %{strategy: strategy, private: %{ash_authentication?: true}})
    )


# and this in render
<Phoenix.Component.form for={@form} phx-change="validate" phx-submit="submit">
      <.input field={@form[:email]} />
      <.input field={@form[:password]} />

    </Phoenix.Component.form>

Customizing ash_authentication for dummies (like me)

I’ve been needing to customize our sign in, register, reset password, and forgot password pages for months. Every time I took a look at the ash_authentication_phoenix pages/code I ran away crying.
