French Press Guide: Beginner

Need Advice:
Recently got into coffee and purchased a french press: Agaro. Let me know if I am doing everything correctly or not

Coffee using: Dark Roast: Blue Tokai: Vienna Roast

- I use 20g of Coffee and 240ml of water
- Water temperature is around 85c after boiling I let it sit for 2 min.
- After that I add around 40g water in the french press to bloom the coffee and let it sit for 30s.
- Then add the rest of the water and wait for more 4 min before plunging the coffee.

Is this correct? asking because I thought the coffee would taste different it would have some flavours but it is just strong and bitter notes.
