How to change Azure AD User invite email template and Accept invite link, Currently it's allowing text only, can we make like HTML

Question

• I am trying to customise the Azure AD user invite, Is it possible to make it with HTML or hyperlinks at least for long links.
• I want to edit the Accept Invitation link, currently it's redirecting to https://myapplications.microsoft.com.

There is option to update the redirect URIs in Azure portal, but I don't see any specific URI for invite email related.
