How to enable experimental features in the classic Power Automate designer and why

Today is the 8th of April and the new Power Automate designer is already some days old. It has a lot of nice features and one feature I like in particular:

Select dynamic content when you write an expression in a flow step:

This is something that is not possible in the old designer. Here you can either select dynamic content or write an expression:

But is this really true? No, it is not!

You can also use the dynamic content when you want to write an expression. For this you just need to turn on the experimental features:

Go to the old designer and click on the settings icon.

Afterwards you select "View all Power Automate Settings":

Then you can turn on the Experimental Features:

And then you can also select the dynamic content in the classic designer while writing an expression:

Tada!

I still like the classic designer more and this feature alone is super useful in my opinion.

I hope it will ease your life with Power Automate as well as it eased mine.
