Ansible module for Brocade/ICX is misbehaving

Question

I've to perform some network automation in my infra using ansible.

When I'm trying to use ansible module for icx switches it seems to be misbehaving.

Playbook I used

---
- name: ICX switch testing
  hosts: test-switch
  gather_facts: no
  vars:
    ansible_user: username
    ansible_password: password
    ansible_connection: ansible.netcommon.network_cli
    ansible_network_os: icx
  tasks:
    - name: show version
      icx_command:
        commands:
          - show version

for this I'm getting below error

FAILED! => {"changed": false, "msg": "skip\r\nInvalid input -> skip\r\nType ? for a list\r\nSSH@ICX7250-24P Switch>"}

when I use enable mode using ansible_become then it gives below error

FAILED! => {"changed": false, "msg": "unable to elevate privilege to enable mode, at prompt [None] with error: timeout value 60 seconds reached while trying to send command: b'enable'"}

I'm not sure why command enable changed to b'enable. Seems some issue with module

ansible version

ansible 2.9.9
  config file = /etc/ansible/ansible.cfg
  configured module search path = ['/root/.ansible/plugins/modules', '/usr/share/ansible/plugins/modules']
