I want to display scoreboard on a sign in minecraft 1.13 or above

I’m using this command to get a sign:

/give @p minecraft:oak_sign{BlockEntityTag:{
Text1:'{"text":"","clickEvent":{"action":"run_command","value":"setblock 43 17 13 minecraft:redstone_block"}}',
Text2:'{"text":"Buy Chicken","bold":true}',
Text3:'["0000000000",{"text":"u2588"},{"text":"u2588","color":"gray"}]'},display:{Name:'{"text":"Custom Sign"}'}
}

but I don’t know how to make custom value with scoreboard in place of zeros on the third line of the sign.

Can someone help?

/data merge block [x] [y] [z] {Text1:"{"score":{"name":"PLAYER_OR_ENTITY","objective":"SCOREBOARD_NAME"},"underlined":true,"color":"dark_red"}"}
