As your company grows you may increase the total number of options in your ESOP pool. For example you may execute a share split or add extra options to your pool when shares increase following a capital raise.
From your left side menu click 'ESOP & Options'.
Click into the 'Settings' menu of your pool and select 'Edit Pool'.
You can increase or decrease the maximum number of options in the pool.
Click the 'Update' button at the bottom of the page to save the changes.
