Start a flow from an email

Hi,

I want to trigger a flow from the body of an email adress. Is that possible? I have the json that I use for triggering a flow from a list, but it doesn't work to insert this into an emails body. 

Ideas anyone?

{ "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json", "elmType": "span", "style": { "color": "#0078d7" }, "children": [ { "elmType": "span", "attributes": { "iconName": "Flow" } }, { "elmType": "button", "style": { "border": "none", "background-color": "transparent", "color": "#0078d7", "cursor": "pointer" }, "txtContent": "Opprett kontraktutkast", "customRowAction": { "action": "executeFlow", "actionParams": "{\"id\": \"<flowid>\"}" } } ] }
