Google Sheets: IF permission matches then Compare Two Cells both with delimited values and find differences

Can Import	Warehouse User,Power User		Can Edit Facility Address	TSA Group
Can Make Return Labels	Power User		Can Edit Sku Information	Warehouse User

Can Receive Remote Crossings	Linehaul Control		Can Set Known Shipper	TSA Group
Can Set Known Shipper	TSA Group		Can Unprocess	Warehouse User
Can Unprocess	Power User,Warehouse User		Can Use Operations Features (Standard)	Warehouse User
Can Use Operations Features (Standard)	Power User,Warehouse User		Create Shipments	Warehouse User
Create Linehaul	Power User		See All Entity Clients	Linehaul Control
Create Shipments	Warehouse User,Power User		See Freight Management System	Linehaul Control
	2		See Shipments	Warehouse User,Linehaul Control

The goal of this is to compared the permissions, if they are a match then check out the Access and see if there is any difference between the matching permission's Accesses.
For example "Can process" would be a match and the difference between the Accesses would be the left user has Power User access that is different from the user on the right.

I am using google sheets which is not too great but for the first part matching the permissions I have:
=IF(COUNTIF($D:$D, $A2)=0, "User 2 does not have permission:", "Both users have permission:")

Having issues first off just comparing the cells with the delimited commas to each other for the difference
Then being able to incorporate it into the first formula so when it does find the match it will then find the difference between the access if any.

Any help would be appreciated as I've been stuck trying different things for numerous hours and can't seem to piece it together
