I want use Lockwise as front end from other password manager because Lockwise is poor in features, such as: tags (like in Firefox), password history, password policies,... I'd like to develop a "extension" for Firefox Android that use Lockwise as front end, keeping the current user login, url and password from other password manager, and If I update a password using the Lockwise so it should update it on my personal password manager.

Thank you in advance.
