How to develop a CRUD for custom posts in frontend not from wp-admin

I am trying to develop a theme where users can create update and delete Projects[which’s a custom_post]; directly from the WP front-end (user side not using the admin dashboard)

Please help me understand how can I create custom posts from wp front-end.

PS: I learned how to create normal posts from front-end and it works fine. I followed this tutorial to do that. :–wp-27172

but for custom posts I am stuck.

I am new here :slight_smile:

Thanks in advance
