Instant flow template is not working on my Sharepoint library

[Adrian123Lujan]

Hello everyone, 

Well, I'm currently working on this Instant flow which main function is to send an approval when a file is created on a library.

Here's my problem, in this site I am setting the template flow correctly (connections and variables) but the flow is missing [red circle].

Afterwards, I created several sites to test if it worked on those. 

I think the main reason why this is not working is the site settings. 

Thanks for your attention all!
