Remove Chat and Share icons from the toolbar / Audio is turned off when joining the meeting (component view)

Meeting SDK
1

How can we remove chat and share icons from the toolbar? I have tried:

const client = ZoomMtgEmbedded.createClient()
let meetingSDKElement = document.getElementById('meetingSDKElement')

client.init({
    zoomAppRoot: meetingSDKElement,
    language: 'en-US',
     customize: {
         chat: false,
         share: false,
     }                 
})

let signature = generateSignature(key, secret, meetingNumber, 0);

client.join({
    sdkKey: key,
    signature: signature, 
    meetingNumber: meetingNumber,
    password: meetingPassword,
    userName: userName,
    zak: userZakToken,
 })

Also, when I join the meeting, the audio is turned off and I need to click the first icon in order to enable it.
