Hi,i am new to salesforce, ineed to add above mention 'Other nan sales' Profile to the Profile.name section in this existing validation please help me with this one.

Validation Rule:

TEXT(Document_Type__c) == 'Product UW Grid' 

&& 

IF( $CustomMetadata.Switch_Setting__mdt.UW_Profile.Enable__c = TRUE , $Profile.Name  <>  'UW/Actuary',  NOT($Permission.Underwriting_Actuary) )

i didnt understand this scenario ,Can any one know how to create this by using flow and how to send chatter to this users SSAM Implementation Specialist or Account Manager ?

project is a Object & Create IP is field

Create a new chatter when: 
Create IP(field)  = 'True'
Chatter the SSAM Implementation Specialist or Account Manager
 @ Person
'The TIC has completed the creation of the IP Package for (Project Name)'
Link to Project
