Thanks for sharing Bora Bora mountain correction.
I am glad you are interested in glider.
To fly a glider well, it is important to stabilize the speed.
Pitch control of the aircraft is very important for this.
In MSFS, updrafts tend to occur on mountain slopes.
When you find an updraft, soar at a constant rate of turn so as not to change speed in it.
If you improve, you can even cross the Alps.
