Is this possible to add many relations between two models? Rails 7

I am working with a database like this :link to db UML

All my models are link to User with 'belongs_to' (User have 'has_many').

My Contact and Society models are link to the Project one by a 'has_many: through:'.

class Contact < ApplicationRecord
   validates_presence_of :name, :firstname, :job, :email, :phone

   has_many :projects
   has_many :societies, through: :projects

   belongs_to :user
end

class Society < ApplicationRecord
   has_one_attached :logo

   has_many :projects
   has_many :contacts, through: :projects
   accepts_nested_attributes_for :contacts, allow_destroy: true, reject_if: :all_blank

   belongs_to :user


end

class Project < ApplicationRecord

   validates_presence_of :name, :value, :description
   belongs_to :society
   belongs_to :contact
   belongs_to :user

end

So when I create a project I can associate a contact and a society to this project. The thing is that I want to be able to associate a contact directly when i create a society. The problem is that I can't access "contact.societies" and "society.contacts" until a project isn't created

My question is, is this possible to add a many to many relation between Contact and Society so that I could be able to associate a society and a contact without created a projet ? Or maybe should I change the association 'has_many: through:' ?

I'm waiting your answers,

Thanks !

Without source code it's hard to know what your issue is, but taking a flying guess, check out the accepts_nested_attributes_for feature, if that doesn't help you then please edit your question to include some source code, show your model associations, and the code you're trying to run to create your project.
