External converters Light.withLevelConfig witout on_off_transition_time feature

[Qianli-Ma]

I'm trying to support a new device, however I am having trouble removing on_off_transition_time if I use e.light_brightness_colortemp_color(), and I am having trouble adding on_transition_time and off_transition_time individualy to extend.light_onoff_brightness_colortemp

Could you post the ext converter here?

Currently I am using the following, however, I would like to add on_transition_time and off_transition_time support. This light does not support off_transition_time

const fz = require('zigbee-herdsman-converters/converters/fromZigbee');
const tz = require('zigbee-herdsman-converters/converters/toZigbee');
const exposes = require('zigbee-herdsman-converters/lib/exposes');
const reporting = require('zigbee-herdsman-converters/lib/reporting');
const extend = require('zigbee-herdsman-converters/lib/extend');
const ota = require('zigbee-herdsman-converters/lib/ota/zigbeeOTA')
const e = exposes.presets;
const ea = exposes.access;

const definition = {
    zigbeeModel: ['CL001'],
    model: 'CL001',
    vendor: 'TERNCY',
    description: 'Terncy Beevon Ceiling Light', 
    powerSource: 'Mains (single phase)',
    ota: ota.zigbeeOTA,
    extend: extend.light_onoff_brightness_colortemp({ColorTempRange: [1, 500],exposes: [on_transition_time] }),
};

module.exports = definition;

I tried using the following

const definition = {
    zigbeeModel: ['CL001'],
    model: 'CL001',
    vendor: 'TERNCY',
    description: 'Terncy Beevon Ceiling Light', 
    powerSource: 'Mains (single phase)',
    ota: ota.zigbeeOTA,
    fromZigbee: [fz.color_colortemp, fz.on_off, fz.brightness, fz.level_config],
    toZigbee: [tz.light_onoff_brightness, tz.level_config],
    exposes: [e.light_brightness().withLevelConfig()],
};

However, since the light does not support on_off_transition_time it's giving me an error when I try to set on/off transition time

Can you make a PR to add support for this device? Than we an address the issue there.
