How to make your mobile phone live & chat minimized="false"

[newavealex]

In my code, I have let minimized="false" but the phone will still show a reduced state, how do I set it up?

This is my code
<call-us
charset="utf-8"
style="position: fixed; bottom: 8px; right: 8px; z-index: 99999;--call-us-form-header-background:#007bc7;--call-us-header-text-color:#ffffff;--call-us-form-height:705px;--call-us-form-width:705px"
phonesystem-url="https://mypbx.3cx.com.tw/"
party="mypbx"
minimized="false"
allow-call="true"
allow-video="false"
allowfocus="false"
ignore-queueownership="true"
authentication="none"
invite-message= "Hello! How can I help you?"
operator-name="support"
allow-soundnotifications="true"
enable-poweredby="false"
ignore-queueownership="false"
enable-onmobile="true"
window-title="test"
animation-style="none"
popout="false"
minimized-style="tab">

</call-us>
