[Android] Can not hide contact us button for RequestListActivity

Hello,

I try to hide the contact us button for RequestListActivity by setting configurations into MessagingActivity builder:

val requestConfig = RequestActivity.builder()
    .withTags("Android")
    .config()

val requestListConfig = RequestListActivity.builder()
    .withContactUsButtonVisible(false)
    .config()

MessagingActivity.builder()
    .withEngines(SupportEngine.engine())
    .withBotLabelStringRes(R.string.app_name)
    .withBotAvatarDrawable(R.drawable.ic_launcher_foreground)
    .show(requireContext(), requestListConfig, requestConfig)

But the button is still visible when launch RequestListActivity by MessagingActivity.

The version of Zendesk SDK I used

messaging: "5.1.0"
support: "5.0.2"

Please help to check it, thanks!
