STM32H562RG LSE crystal oscillation issue.

I am using a STM32H562RG and my project involves timing, for which I am using an external LSE crystal. I know that the STM32H562RG can adjust the LSE drive level. I used STM32CubeMX to generate the code. I noticed this code comment.

/** Configure LSE drive capability
* WARNING: Only applicable if LSE is disabled.
*/

I don't understand. What should I do? When I used STM32L431 before, there was no such code comment.
Because when I set the level to HIGH, the LSE crystal of the STM32H562RG still does not oscillate. I don't know what I am doing wrong.
