Welcome to the community.
First of all, please disable your caps-lock. All-caps posts are considered spam in pretty much every forum community.
Second of all - assuming you are talking about Phasmophobia since you didn’t specify a game - the link is right at the top of the trainer, in the message that you are forced to read before you can press the Play button for the first time.
Pressing that link takes you to this post with a download file attached to it: Phasmophobia Cheats and Trainer for Steam - #828 by MrAntiFun.
If your post was not about Phasmophobia, read the message at the top of the trainer for whatever game it is you were referring to, or open your own thread in the Support section of the forum, minus caps and specifying which game you are referring to.
