Remove Sharing Link for SharePoint Folder

[Joe_]

Dear Power Automate Community,

for lack of skill (and being able to find a solution via searching the topic) I turn to you for help 😃

My idea is the following: I am building a SharePoint site for customers to upload data and fill a questionnaire. For each customer, there are 5 contributors / groups of contributors. What I have managed so far is:

- a SharePoint list where we would enter the Client Name, the Year Under Review as well as the internal Responsible for the client plus the 5 client (sub-) contacts who need to enter their data in 5 columns;

- a flow that checks whether the client is new or had a folder in the previous year, then either copies the previous year folders for the client to use as a template or copies an empty template folder if it's a new client and lastly grants access to the 5 groups (really just email addresses) from the list of clients; and

- a flow that checks whether the creation and modification date are equal. If they are, it decides that it is a new client, creates an archive item and then terminates, if they are not, it decides that it is a modification, creates an archive item and compares whether the email addresses are identical for each of the 5 columns between the previous archive item and the modified item. 

This is how far I got it working. Now my issue: I need to remove people that were in the previous (aka the latest archive) item and add the people that are in the newly modified item to the access list. The easiest, in my understanding, is to remove the access link all together and create a new one for the subgroup.

I have checked the following resources and did not get anywhere:

- https://tomriha.com/how-to-remove-permissions-from-a-sharepoint-folder-with-power-automate/

- https://powerusers.microsoft.com/t5/Building-Flows/Stop-sharing-from-folders-using-power-automate/td...

- https://powerusers.microsoft.com/t5/Building-Flows/Delete-all-sharing-links-of-a-folder/td-p/862697

If anything, I may use a temporary manual solution as those changes in contact should be rather limited in nature and therefore, as long as the flow gives access to the new contact and sends me an email to remove contact A from the access list of folder X, it should be fine. That being said, any automated solution to this would of course be greatly appreciated.
