Is it possible to send bold text in JSON push notification body using Firebase Cloud Messaging?

I am using Firebase Cloud Messaging to send push notification to IOS and Android devices. I would like to send some text in message body, which has a part of it bold. That's how my JSON looks like now for android push notifications:

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "body":"Some plain text THIS TEXT SHOULD BE BOLD some plain text"
    }
  }
}

Now I would like to see the message in my push notification like this: "Some plain text THIS TEXT SHOULD BE BOLD some plain text"

Is it possible to do so?

You can send as Markdown and make your Android client parse it, so your message would be something like

{
  "message":{
    "token":"bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
    "notification":{
      "body":"Some plain text **THIS TEXT SHOULD BE BOLD** some plain text"
    }
  }
}
