You can distribute rewards from the Allocate tab. When you distribute the rewards from an allocation the Recipient Address is sent TruMATIC.
To distribute rewards to a single recipient, simple click the Distribute button for the corresponding row of the table. The amount that will be distributed is the amount of TruMATIC in the Undistributed Rewards column.
Reward recipients will receive TruMATIC which they can convert into MATIC by withdrawing from the vault should they wish.
You can distribute all rewards that are outstanding by clicking the Distribute All button. This is more gas efficient than clicking each of the Distribute buttons in turn.
The total amount that will be distributed when you Distribute All is the number of Rewards Owed.
