In VMD the first letter indicates the element. So a capital H would sign an atom as hydrogen.

Thank you for the quick reply.

No, it does not recognize. But through Keywords: Name or type , I know which atoms are hydrogen.

Can you please explain more how I can set the atom names for recognizing H-bonds?

Does VMD recognize the hydrogens in your system? If not, then
the issue is probably as simple as just getting the atom names
set so VMD knows what they are.
