MATLAB: How to rename connections between blocks in Simulink

rename connectionsimulink

How to rename connections between blocks in Simulink. Below is code to rename GotoTag in Blocks. But also to rename connection between blocks is required. In attachment is the corresponding Simulink model with a "From" and a "Goto" block that should be renamed with the code below. Additionally is a "Constant" block as dummy connected to the "Goto" block. This connection to "Goto" block should also get the new name of "Goto" block.
CurrentName = "A";
RequiredName = "B";
b1 = Simulink.findBlocks('model','GotoTag',CurrentName);
for i=1:length(b1)
    set_param(b1(i),'GotoTag',RequiredName);
end

Hello
I have attached a model that is easier to understand.
Please try following script.
CurrentName = "A";
RequiredName = "B";
b1 = Simulink.findBlocks("model","GotoTag",CurrentName);
for i=1:length(b1)
    set_param(b1(i),"GotoTag",RequiredName);
    
    blkType = get_param(b1(i),"BlockType"); % get block type 
    potH = get_param(b1(i),"PortHandles"); % get porthandle
    
    if strcmp(blkType,"Goto")
        lineH = get_param(potH.Inport,"Line"); % get LineHandle

        if isequal(lineH,-1) 
            % not connect

        else
            set_param(lineH,"Name",RequiredName);
        end         
    elseif strcmp(blkType,"From")
        lineH = get_param(potH.Outport,"Line"); % get LineHandle
        if isequal(lineH,-1)
            % not connect
        else
           set_param(lineH,"Name",RequiredName);
        end 
    else
        % nop        
    end
end
