Fitting a throttle to a Boostbike?

Please excuse my very rudimentary diagram and obvious lack of technical understanding (I haven’t had chance to even separate the plug to count the pins because I’m currently out of action with covid and bored/thinking).
My situation is this:-
I’m 99% happy with my Boostbike conversion. After years of being told my frame shape was incompatible with the kits available, I was over the moon to finally get my bike converted. But I have a dodgy hip and this can “go out” at any time or place and for no apparent reason. When it does, pedalling is extremely painful and the conversion doesn’t include a throttle.
So, can the kit be modded to include a thumb throttle? I’m not looking to be able to zip around at full speed everywhere, just be able to get home without having to call a taxi (again!).
My overly simplistic thinking is that the only thing needed is a live feed from the battery to the throttle and a feed from the throttle into the wiring loom that bypasses the controller?
Am I being totally naive thinking it might be this simple?
Has anyone managed to fit a throttle and, if you have, how?
Yours thoughts are invited.

It's not as simple as that. The controller needs to have a specific connector for a throttle and be programmed to work with it if you want a working throttle. I'm pretty sure that your kit doesn't have such a connector. Only the controller can make the motor work. There's no way to bypass it.

On any other kit that has a separate pedal sensor, there are ways to spoof the pedal sensor signal, but the Boost kit has some sort of pedal sensor inside the motor, which prohibits that.

In summary, you bought the wrong kit if you wanted a throttle or power without pedalling.

Thank you.
To be fair, I didn't want a throttle... I just completely underestimated how painful my hip would be trying to pedal.
