CentOS: Wireless adapter not found

I have installed CentOS 7 on my new HP laptop which has Realtek Semiconductor Co., Ltd. RTL8822CE 802.11ac PCIe Wireless Network Adapter which I found out using ‘lspci’. But I can’t connect with wifi. It says wireless adapter not found. I have searched in libfirmwarertlwifi but cant find rtl8822ce file. My laptop don’t have LAN port, so I need wifi to work.
