• The account pub key format can be one of: acct_vk, acct_xvk, xpub https://cips.cardano.org/cips/cip5/ The flow to generate I'm understating is:
• Get stake pub key from account pub key
• Get stake address from stake pub key

But currently I don't know how to use the lib to get stake pub key from account pub key. The only way I see is CIP1852
