Custom policy add overlay message

Question

I am using a custom policy for password change. I am following the custom policy mentioned here https://learn.microsoft.com/en-us/azure/active-directory-b2c/add-password-change-policy?pivots=b2c-custom-policy

Is there any way to add an orchestration step that displays overlay message that password has been changed before SendClaims step.

Between step 4 and step 5, add an orchestration step to call a selfAsserted technical profile.

Demonstrated here: Add a step (you can remove the preconditions node) https://github.com/azure-ad-b2c/samples/blob/master/policies/invite/policy/SignUpInvitation.xml#L165

SelfAsserted technical profile with a message https://github.com/azure-ad-b2c/samples/blob/master/policies/invite/policy/SignUpInvitation.xml#L110

You must have one output claim in the selfAsserted technical profile. Here a claim transform is used to generate a string to display to the user.

All options available to a self asserted page https://learn.microsoft.com/en-us/azure/active-directory-b2c/self-asserted-technical-profile

Apply custom html to the page to deliver the message/branding https://learn.microsoft.com/en-us/azure/active-directory-b2c/customize-ui-with-html?pivots=b2c-custom-policy
