How can I deposit money into paper account?

I want to have money in the paper account to start testing some trading. How can I add money to paper account?

@Mehdi_Zare One can initialize a paper account with whatever initial cash one wishes. Open your paper account then click on “Reset Account”. A window will pop up (as shown below) where you can enter starting cash. There currently isn’t any way to add, or withdraw, cash from a paper account. One can only set the initial starting cash.
