Battery Builder option is unavailable in apps tab under simscape of MATLAB toolstrip.

(using online matlab)

While completing Task under "Build Battery Pack using Battery Builder" on simulink, i am not getting option Battery Builder as told in task 1 i.e. if i navigate the Apps tab> Matlab toolstrip > Simscape > Battery Builder (it is not available).

I am able to add manually on MATLAB using command. But unable to see on simulink while the battery add-ons has been added.

Please let me know if someone has the answer.
