How to add additonal shear supplementary reinforcement? Four rebars left and right of the anchor group within 0.75h_ef are needed.

I have added shear supplementary reinforcement to the concrete.
I got a notification asking to add: Four rebars left and right of the anchor group within 0.75h_ef are needed.
How can I add additional shear supplementary reinforcement left and right, please?
Cheers,
Lucia
