I am tring to upgrade Asterisk_Click2Dial from v7 to v8 , when i install Asterisk_Click2Dial module in v8 ,

No Dial button shown on customer from in front of Phone and Mobile Field (In V7 Dial Button shown  on customer from in front of Phone and Mobile Field)

And No Dial Icon shown in menu bar before User Menu(Preferences,Log out Option) (In V7 Dial Icon shown in menu bar before User Menu)

When i did some RND Then i found i need to change js,css,and xml file of Asterisk_Click2Dial  in V8 i want to know how can i do that to display Dial Buttuon and Dial Icon in Odoo Gui.

Thanks
