Plumbing – Hand-Spray Bidet Connection didn’t work due to smaller existing pipes

plumbing

just received my hand spray bidet set i ordered online. After trying to connect the set, the existing pipes found on the installed bidet are smaller than the T-valve connecters. Both the female thread and the main water supply pipe. Can anyone please help with what type of connections i might need to install it properly. The images below might show exactly what i am facing. Many thanks

Look for a compression fitting.in the plumbing department. Something like this as it's hard to guess the sizes by the picture.
