How do I appoint my joint executors where the remaining can continue to be the joint executors (or sole executor if only one remains) if any of them is unable/refuse to act?

In the Appoint People tab, under Appoint Executor, choose your joint executors by adding them under the "Main Executor" section. Leave the Substitute Executor section blank.

In the above example, if B is unable/refuses to act, A and C will continue to act as the only joint executors. If A and C are unable/refuse to act, then B will continue as the sole executor of the Will.

Under the Select Clauses tab, toggle on Other Instructions and key in the following:

If ANY of the following personnel:

- my {Relationship}, {Name}, {Identification Number/details};

refuses to act or is unable to act, or his/her appointment does not take effect for any other reason, I appoint the remainder of them to be my joint executors of my Will, or if there is only one remaining, for him/her to be the sole executor of my Will.
