Hi @Christian Labraña ,
Our forum is an English forum, it is recommended to post in English to avoid misunderstandings. According to machine translation, your question is that you want to open the file through the office app, but don't want to download it locally, in case the file is out of sync.
SharePoint is by default like this: when you select open file in app in sharepoint, usually open the file directly using the office app for editing (the content will be synced). But according to your description, it seems that you will automatically jump out to download to local. I can't reproduce this situation, but I found the thread that had the same problem as you. He eventually solved the situation by switching browsers, or installing the Microsoft 365 extension in Chrome. Would you suggest you try it and let me know the results?
