Autocompletion in Ionic 5 ( Angular ) using VS Code

Hello,

i am Developing by using VS Code for IONIC 5 ( Angular ).
Everything works fine so far.

The only Extensions i have installed is this one : https://marketplace.visualstudio.com/items?itemName=johnpapa.angular-essentials

To use Code Completion i always have to press Ctrl+Space to get code proposals.
I was expecting to get code proposals automattically.

Are the another Extensions i have to install to get AUTOCOMPLETION for Ionic5 using Angular ?

Thx in advance
