How to add a button with a link for Facebook that opens up the app?

So I have this page on my website where I am adding buttons, for example "Ir a Facebook"  (go to facebook), which is a button I want to use where when people click it they are sent to the Facebook App and the user/profile for this business. Currently I am using the link as is: https://www.facebook.com/trestylos but it ends up opening the mobile browser and this doesn't work for me. What can I do fix this? I want the link to open up the Facebook App for my visitors so it is easier for them to just click and LIKE/FOLLOW this profile. What can I do? Thanks in advanced for the help!

Have you tried adding Messenger.com link yet?

I'm not sure what you mean but I'm happy to explore it. How do I have to go about this suggestion of yours? Do I get this link from facebook?

Try messenger url, I think it will open an app on mobile

I think this is a step in the right direction but it doesn't solve the issue. So It opens up Facebook Messenger, but not the Facebook App. I was told that there was something called "DEEP LINK" which meant that if someone clicks on that link on their mobile browser they can open their facebook app and see the desired facebook profile all in the same "click". 

Are you familiar with this? Thank you so mucho for your help, by the way!!!
