no variants are available in from position

I HAVE BEEN TRYING TO SEND VARIANT FROM POSITION CHALLENGES FOR A LONG TIME.EVEN IF THEIR IS AN OPTION FOR VARIANTS, I AM UNABLE TO SEND CHALLENGES AS SOON AS I CHOOSE A VARIANT. IF SOMEONE KNOWS WHY THIS HAPPENS THEN PLEASE TELL ME.

Is your caps lock key broken?

NO IT IS NOT

From Position isn't supported for variants.

@shauryanilesh
Lichess doesn't have From Position variant challenges. And lichess doesn't plan to implement the system anytime soon.

Well, about an year ago, I tried challenging from position of a variant to my friend but it didn't work and then I came to know about this.
I hope it comes at Lichess.
