Configure Dimmer Button

I have the Ikea Tradfri Wireless Dimmer in my home assistant. For this and many other dimmers I have searched the internet but nowhere is it shown how to configure an automation in Home Assistant to Start Dimming and Stop Dimming where it increases or decreases for example the brightness.

This button for example has the following options to use in an Automation:
Dim Up = Press button continuously/longpress
Dim Up = release after long pressing this button
Dim Down = Press button continuously/longpress
Dim Down = release after long pressing this button

How can I without complex blue prints, node red and other advanced/difficult ways using the standard options in Home Assistant to use dimmer buttons for dimming.

Now I would have to keep such devices connected to their original bridge to keep dimming working.

Please help or even better if you are a youtube channel owner, create a nice video. If not but you provide simple steps on how to do this I will create such a video myself.

ps. If I use the increase brightness option in home assistant it just increases the brightness with one step. It does not continuously increase the brigness until I release.
