Cannot use Effects properly

[SeshXD]

As in shown in the screenshots I don't have that rectangle button so I cannot use most of  Effects.

Does anyone knows a way to fix it ?

What rectangle button are you referring to?

As I see you don't have that button too but I don't know why,guide that I am watching is using a button that makes him use write-on addon easily.

I am not sure If I am allowed to share here but YouTuber Orange83 has a guide for text effects https://www.youtube.com/watch?v=Ag7Y12qP9FQ can you please look at 2:20

The rectangle (as in transform icon) has been removed from newer versions.

Just highlight the name of the effect in the Effect Controls in order to use in the Program Monitor.

Beware of what tutorials you are watching.

Many things have changed over time.
