How to integrate angular 7 with confidential access type of open id connect

Hi,

I am new to keycloak application just needed some help.
I have angular 7 application need to integrate with keycloak client as confidential access type.
As refereed many documets it states that there is no support for confidential access type for javascript / HTML client.
My requirements is to enable authorization for front end.
Please suggest any guidance or how we can proceed , is there any better ways
