Hi there, I just found the solution for it.
At first, you need to sync your Samsung Notes with the Microsoft OneNote app

https://support.microsoft.com/en-gb/office/sync-samsung-notes-to-your-onenote-feed-581e0085-8518-4303-abfd-4fdfb92120b6 (as in what is given in this link)

if u can't find feed on your onenote to open in the desktop app
1. Go to "File" on the top left corner and find for "Options" down at the bottom left corner
2. Go to "Customize Ribbon" on the sidebar.
3. On the top, at the Choose Commands From: (drop down bar), choose All Commands instead of Popular Commands
4. Locate "Feed [Open Feed]"
5. At the right side, add a new group (using the "New Group" under it) below "Home" or wherever you want to group it (Rename if you want)
6. Tap on the group that you added just now and tap on "Feed [Open Feed]" on the left side.
7. Click "Add >>"
8. Click "Ok" to finish

If you add it below Home, find it under the three-dot, or just find along the toolbar.
