title: ABP Add User's Custom Property from AppUser to Claims
body: <p>I'm trying to add a claim &quot;business_id&quot; where the value will be taken from AppUser's custom property of &quot;BusinessId&quot;. Only resource that I'm able to find relating to this topic, covers on how to add custom claim: <a href="https://github.com/abpframework/abp/pull/7998" rel="nofollow noreferrer">https://github.com/abpframework/abp/pull/7998</a></p>
  <p>Problem I can't use get service for ABP's &quot;IdentityUserManager&quot; in the approach because it does not contain the custom property added in AppUser.cs.<br />
  I did attempt to use asp.net's UserManager instead. But there is a lot of other dependency involved like IUserStore etc.</p>
  <p>Any pointers for this? Thanks in advance.</p>
