Embraco EGU 70HLC Prongs??

Novice here! Forgive the non-tech rambling!
I have an old top freezer maytag ptb1753drw. The Relay Overload start device fried.
I bought a replacement called a Kenmore Maytag Refrigerator Relay Overload Start Device, with 3 wire connections on one side and 3 receptacle holes that attach to the compressor. 2 holes are round and connect to the white and orange wires and there’s a hole looks is like a mini jack-o-lantern smile with a round hole just below it which connects to the blue wire. The orange and white wire holes and jack-o-lantern hole were completely scorched. The blue wire did not fry so the round hole below the jack-o-lantern hole didn’t fry so badly.
I replaced the burnt flag connections and am ready to plug the relay onto the Embraco EGU 70HLC compressor. However, I am not sure what the prongs on the compressor should look like.
2 are plain round prongs and one has a weird rectangle piece of metal on the end. I don’t know if it’s supposed to be there or if it’s from the guts of the fried overload relay. It looks rather melted.
I found the 2009 thread: "Compressor Connections (Relay/Overload Protector)" thread and richappy’s answer that "The start device may be arc welded to the compressor pins. Bust off what you can and use a dremel with grindstone to dress up the compressor pins."
Is this what I’m seeing? Do I need remove it? Do I really need a dremel?
Does anyone have a pic of the Embraco EGU 70HLC compressor prongs? Should they just be 3 plain round prongs?
Thanks to any info and your patience for reading this through!
