Remove nodes in a graph based on label name instead of index

I am fairly new to Matlab and trying to modify a network graph.
I want to remove nodes in a graph based on node's label name instead of the node's index. Using the screenshot as an example, I would like to remove node that has name of '12'(underline in blue) instead of node that has an index of 12(underline in red). Is there a way to do so?
I try
G = rmnode(G,G.Nodes.Name=='12')
But get error message: Operate '==' is not supported for operands of type 'cell'.
Thanks for any suggestions.

Ran in:
B = graph(bucky, string(1:60)); % Use '1' through '60' as names
head(B.Nodes) % Show the first few node names
ans = 8×1 table
Name _____ {'1'} {'2'} {'3'} {'4'} {'5'} {'6'} {'7'} {'8'}
B2 = rmnode(B, '42');
B2.Nodes(40:45, :) % No node '42' in the modified graph's Nodes table
ans = 6×1 table
Name ______ {'40'} {'41'} {'43'} {'44'} {'45'} {'46'}
