I think currently you are sending everything from Power BI to Power Automate.
You will have to first choose the fields you want to send to Power Automate, you will have to tick the values, that you want to send to Power Automate, or if you have to send everything, select everything. Then you can make the json structure that the person has done in the above video. Its pretty easy to make.
So lets say you have 3 fields: name, id and address. Just write it as like this:
{
"Name": SelectDynamicFieldForName,
"Id": SelectDynamicFieldForID,
"Address": SelectDynamicFieldForAddress
}
Watch the following video for more reference, how you can select values from Power BI to pass to Power Automate:
