I want to show button A or button B in a column depending on value in another column.

one button should start a flow, another button should launch a hyperlink also I need to add other buttons.

I have spent the day googling and fudging and the current code shows nothing, if I remove the code for button B then button A works.

```
{
    "elmType": "div",
    "children": [
        {
            "elmType": "button",
            "txtContent": "New ",
            "customRowAction": {
                "action": "executeFlow",
                "actionParams": "{\"id\": \"be40d280-88df9a875fa\"}"
            },
            "style": {
                "display": "=if(  ([$Kent] == 'A' ), 'block', 'none')"
            }
        },
        {
            "elmType": "button",
            "txtContent": "New",
            "attributes": {
                "target": "_blank",
                "href": "='URL'"
            },
            "style": {
                "display": "=if(([$Kent] == 'B'), 'block', 'none')"
            },
        }
    ]
}

```
