Touchy Trio Sudoku (Daily Sudoku League #139)

I am experimenting with the different types mixing with the Trio Sudoku. Earlier I have created some puzzles likes Non Consecutive Trio Sudoku and UnTouch Trio Sudoku. This Touchy Trio Sudoku is the another type which I liked very much. Regarding today's puzzle, I wanted to create this Sudoku type without giving any hints and I was successful up-to some extent. However to avoid Sudoku being non unique, I have to give couple of hints. However to maintain symmetry, I tried to put corresponding digits in the opposite end which lead to destroying the beautiful logic this Sudoku need to solve it. So later I removed these hints to retain the minimum hints which is required to solve this Sudoku. I will mark this Sudoku as the tough one and beginner Sudoku players first should try solving few Trio Sudoku and Touchy Sudoku puzzles before attempting this Sudoku puzzle.
This Touchy Trio Sudoku, I am posting as my 139th Sudoku in The League of Extraordinary Ladies & Gentlemen.
Rules of Touchy Trio Sudoku
Classic Sudoku Rules apply. Cells with circles must contain the digits 1, 2 and 3. Cells with squares must contain the 4, 5 and 6. Blank cells must contain the digits 7, 8 and 9. Additionally each digit has at least one consecutive adjacent (sharing edges) neighbour.
