Its the Stockfish information.
It tells you information on how the number +0.2 was calculated. Level 30 which is the deepest level on Stockfish used on this platform. Thus indicating the score is very reliable.
Ok thx but I asked for the red square at the left
It's a new design choice and I guess it just means that stockfish is in the process of calculating

Hover the mouse over it and it shows "Pause".
When you press it SF stops calculating and the red square becomes the + sign.
Oh, didn't know, it doesn't work like this on mobile. Thank you @Viohl
It's a stop button inspired by 80's and 90's audio devices.
oh, thank you for your answers !
I just want to add that the red square is distracting me and i'd like to suggest changing the colour to something less bright. When going trough a game it flickers between bright red and blue drawing the attention away from the analysis.
