Check if database supports transactions using FireDac

How to check if the DBMS supports transactions using FireDac components?
I usually use something like the following code to perform a transaction in my DAO class using dbExpress.

...
connection: TSQLConnection;
dbxTransaction: TDBXTransaction;
... 

if (connection.TransactionsSupported) AND ((not connection.InTransaction) OR (connection.MultipleTransactionsSupported)) then
begin
    dbxTransaction := connection.BeginTransaction(TDBXIsolations.ReadCommitted);
end;

      

        
        
        
      

    

So what are the properties of correspondents in FireDac that I use in dbExpress:
TransactionsSupported


InTransaction


MultipleTransactionsSupported

Thanks in advance.
