WeaveDB transaction ID

I designed a system where Doctors and Patient can actually meet each other in a decentralized manner, use weaveDB to save my project… But I created a dashboard where by if u have registered, u can automatically view your details and only u have access to those details, so I want to ask how do I use my transactioniD to fetch data from the weave DB collections

I consulted their documentation but nothing seems to be working at all

I have tried multiple things but nothing seemed to be working I use the get method from their documentation but nothing worked at all, pls help me if you are just seeing this message thank you very much and GOD bless you
