According to the upper url I have some questions:
1. The free plan has no lean cli ability but I can run the lean commands such as “lean backtest xxx” or “lean cloud backtest xxx” successfully. What do you mean actually?

2. The free plan has no API Access. What's it ?

API Access

Use QuantConnect's API to create projects, run backtests and read backtest results.

3.  According to old youtube videos, there was “lean gui” to show the plotting result of backtesting but it was deprecated since 2019. When you run “lean gui start” it says there is a VScode extension to replace it. Can we see the plot result locally via this extension?
