Can't see where a transaction came from

User flow:
Someone sent us a pile of XCH by mistake.

I want to refund it.

I go into the chia wallet 1.6.2 gui.

I only see the transaction listing of me receiving it, and the block number / transaction height.

Can't find the address it came from. How do I refund it without going to the CLI?
