Go to the Equity Plans > Grants page, search for the stakeholder whose options need to be exercised and click the arrows on the right-hand side. You will then be able to input the Date and Number of options to be exercised as well as Run templating and signature workflow.
You can also click on the row with the Stakeholder's name to open it. A row grouped by Grant # will appear. You can also click on that and an individual grant will appear.
In that last row, you can click on the 3 dots as well and exercise from there.
