There in no "Play" button to push

Welcome to the community.

You need to read the information given in the trainer, as @ptondo said.
Here’s a quote from earlier in the week:

@Ravenfyre

• Open the trainer in the WeMod desktop app. As instructed in the top-right of the trainer (shown in red below), read the note and then dismiss it (using one of the two options shown in yellow below).

• The “Read Notes” button will then change to a “Play” button. Press this.
