Replace a standby node permanently (reset standing_in_for)

I have a customer cluster who had a long term outage requiring them to activate a standby node for several weeks. Now they have fixed the dead node and would like that to be the new standby node while converting the standby / standing_in_for node to active status. What is the sequence of commands needed to reset the status - in this case here is the node table showing node0041 as the old standby node, want to make it permanent ACTIVE while node0003 should be active standby:
select node_name, node_state, node_address, node_type, standing_in_for from nodes order by node_name;;
node_name | node_state | node_address | node_type | standing_in_for
