SharePoint List Button

[VeeExcelLearn]

How do I make a button or some sort of an event where if I press a button it will clear a column item in a row.  For example, in the visual below I want to press a button that would clear the word "Stop" in the Stop column.  What I am trying to do is limit the amount of flow runs.  Right now the flow is set to stop running if it sees the word Stop in a row.  As you can see, we have updated the column to Megan but the notes that are coming in are for Ibrahim.   So If I have a button that would clear the word stop.  It would trigger the event to run and update the Notes for Megan.

I hope this makes sense.

@VeeExcelLearn You can use JSON column formatting for your requirements to clear value in "Stop" column. Use JSON in this format: 

{
    "$schema": "https://developer.microsoft.com/json-schemas/sp/v2/column-formatting.schema.json",
    "elmType": "button",
    "txtContent": "Clear Stop",
    "customRowAction": {
        "action": "setValue",
        "actionInput": {
            "Stop": ""
        }
    }
}

@VeeExcelLearn Here's Microsoft official documentation for JSON formatting where you can find all syntax and styles (CSS) you can use in JSON formatting: JSON formatting-syntax-reference
