How do I delete an Instagram post?

I have Instagram on my laptop and phone (web version)

I googled and there's the 3 points then on delete, but for me there's no deletion

IG was originally released for mobile phones.

I think you will find the delete button there.

There's no one that's the problem

Did you open it in the app?

I don't have the app, but the web version, so it looks different

Exactly for that reason: IG was developed for the cell phone. As an app.

There are all the main functions of the app. The web version was added later and does not have all the functions…
