I mean something like this:
{
"persistent_menu":[
{
"locale":"default",
"composer_input_disabled":false,
"call_to_actions":[
{
"title": "📚 bla",
"type":"nested",
"call_to_actions":[
{
"title":"📚 bla",
"type":"postback",
"payload":"SeeCourses_PAYLOAD"
},
{
"title":"🔖 bla",
"type":"postback",
"payload":"SeeMyCourses_PAYLOAD"
},
{
"title":"🔎 bla",
"type":"postback",
"payload":"SearchForCourses_PAYLOAD"
}
]
},
{
"title":"📆 bla",
"type":"postback",
"payload":"SessionsDateAndTimes_PAYLOAD"
},
{
"title":"⚠ bla",
"type":"postback",
"payload":"InsituteInfo_PAYLOAD"
}
]
},
{
"locale":"ar_AR",
"composer_input_disabled":false,
"call_to_actions":[
{
"type":"postback",
"title":"Change Language",
"payload":"Change Language"
}
]
}
]
}
