Hi @Anonymous
Can you share details on the trigger that you are using? If it is of type manual then you can define the flow to use the connection of the person who triggered the flow and then the modified column will show the person who triggered the flow.
If not and you have provided a service account type, it is not possible to identify the user that triggered the flow (for example in case of when an item is created or modified etc. and you modify the item in the flow then it will save the last modified person that will be the flow author)
If you can share more details, we may be able to assist you better with this.
Hope this Helps!
