Hi @Victoria,
Based on your description of your requirements, here are some flow configuration details for your reference:
Step1: You could add a Yes/No type column called UpdateSwitch, and set the default value as Yes. Switch it to Yes if a user needs to update every time.
Step2: Create a condition under the trigger of the flow you created, and judge the column UpdateSwitch whether it is Yes.
-If true, continue the next steps.
-If false, do nothing.
Step3: After adding a link in a list to a document, update the item set UpdateSwitch value as No.
Or you can determine whether to create and update time by adding a condition is the same,
-If the same, is a new item
-If not the same, it is the previously created files.
So that you can avoid subsequent updates in the new item of the item to trigger the flow again, but this method is only suitable for the new item if it needs to frequently update the list, do not recommend to do so, this method is presented here for reference.
I hope it can help you. If you still have questions, please contact us.
