If harrys or TJ hasn't replied, nobody has data on this one of thousands of brands and models of controller.
If your controller has a 3 input connector, of which the outer two pins are 5 v, you might be able to plug a throttle into it. The speed signal input voltage on the dataplate offers some hope that is true. In that case the throttle you buy has to match that connector.
If not then a picture of the connector your controller uses to connect to the motor, display, and battery may help one of the above to identify a suitable replacement controller.
These connectors are not sold individually in the US. If you get on alibaba they will be glad to sell you 100000 of some connector, but it is too much trouble for them to provide a dimensional diagram to prove their product matches your needs.
I've found not even shimano, sram, & sun provide dimensional diagrams of, for example, $20-80 sprocket clusters or $20-30 derailleur takeups. I bought and threw away 4 sprocket clusters in 2019 due to them not fitting. One more reason I seriously detest buying anything from the orient. No option on bike motors, mahle sells their swiss model only by the containerload.
