Azure B2C custom policy - Is there a way to display a claim in a ClaimsProviderSelection orchestration step - azure

Question

I am currently working with Azure B2C custom policies for my Auth flow.
I have a ClaimsProviderSelection orchestration step which shows the user two options:
Send code to their MFA email saved in authentication methods
Lost Email
What I would like to do is show the users email address through the use of a ClaimProvider in either the display text, or the button itself (see below)
If this is not possible, then I would love to be able to add a 'lost email' button on the verification control page itself - like so:
From what I have seen though, it seems this is only available with 'ForgotPasswordExchange' (as seen here: https://learn.microsoft.com/en-us/azure/active-directory-b2c/add-password-reset-policy?pivots=b2c-custom-policy) for passwords and not authentication methods.
If anyone has any experience with customizing ClaimsProviderSelection steps, or adding custom links on orchestration steps your help would be greatly appreciated!
See below for code examples:
Orchestration step:
<OrchestrationStep Order="2" Type="ClaimsProviderSelection" ContentDefinitionReferenceId='api.MFAselections' >
<Preconditions>
<Precondition Type="ClaimsExist" ExecuteActionsIf="false">
<Value>strongAuthenticationEmailAddress</Value>
<Value>strongAuthenticationPhoneNumber</Value>
<Action>SkipThisOrchestrationStep</Action>
</Precondition>
</Preconditions>
<ClaimsProviderSelections>
<ClaimsProviderSelection TargetClaimsExchangeId="MFAVerifyEmailAddress" />
<ClaimsProviderSelection TargetClaimsExchangeId="LostEmailExchange" />
</ClaimsProviderSelections>
</OrchestrationStep>

Answer 1

For anyone who is coming across this - this is what I ended up doing:
Add ContentDefinitionParameters with claim to UserJourneyBehaviors in your RelyingParty
<ContentDefinitionParameters> <Parameter Name="email">{Claim:maskedEmail}</Parameter> </ContentDefinitionParameters>
Use JS to grab email claim from source code, and insert to HTML
const parser = new URL(SETTINGS.remoteResource); let email = parser.searchParams.get('email');

Answer 2

Have you tried to do Output Claims transformation on the email, create a claim of type string, then append the email to it, in a previous step. And display that on the screen.
