If your driver is meant for a reverse clicky, you can wire the NC (“normally closed”) contacts in series with your latching on-off switch.
Click the light on with the latching switch, change modes with brief presses of the momentary switch, click off with the latching switch.
Alternatively, you could buy a Convoy S2+ host and set the tailcap into your light base. Then you have a replaceable reverse clicky Omten 1288 switch to work with, just like a flashlight. Depending on the host colour you choose, the tailcap will have a rubber switch boot or a metal push plate, so you can pick your preferred look.
