I get this error while import the module:

Error while importing module 'pos_margin_sale'.  
Module loading pos_margin_sale failed: 
file /tmp/tmp5bby2hp9/pos_margin_sale/security/ir.model.access.csv could not  be processed:  
No matching record found for external id 'model_sale_confirmation_wizard' in field 'Model'  
No matching record found for external id 'model_wizard_margin_product'  in field 'Model'  
Missing required value for the field 'Model' (model_id)  
Missing required value for the field 'Model' (model_id)

here is my csv security file: 

id,name,model_id:id,group_id:id,perm_read,perm_write,perm_create,perm_unlink

access_sale_confirmation_wizard,pos_margin_sale.sale_confirmation_wizard,pos_margin_sale.model_sale_confirmation_wizard,,1,1,1,1

access_wizard_margin_product,pos_margin_sale.wizard_margin_product,pos_margin_sale.model_wizard_margin_product,,1,1,1,1

here is my model pseudo code : model sale_confirmation_wizard

class SaleConfirmationWizard(models.TransientModel):   ​
_name = 'sale.confirmation.wizard'   ​
_description = "Sale confirmation wizard" 

message = fields.Text(string="Message")

model wizard_margin_product

class WizardMarginProduct(models.TransientModel):   
​_name = 'wizard.margin.product'   ​
_description = 'Set margin on every product'

I have added it in manifest file and also in init of the model i also have double checked the sequence and typo error, all was right but still i am getting this server error

but on import module have note like this :
Note: you can only import data modules (.xml files and static assets)
