The forward is among the impact substitutes for the Lionesses and believes that the "positive clique" can make the difference as the team looks to defend their European crown.
Referring to Beth Mead and Aggie Beever-Jones clicking their fingers after scoring against Wales in the group stage, Kelly said: "It’s great. We have a little group of us, the finishers, the positive clique we call it. We said if one of us comes on to score then we should do that as our celebration.
"We work really hard on the training pitch, in the gym, making sure we’re prepared when we go on to the pitch and we have a great group of girls so it’s about enjoying the whole experience as a group."
Kelly famously scored the winning goal in the Euro 2022 final as the Lionesses won on home soil but she is determined to enjoy more great moments with the national team.
The Arsenal star said: "It’s been great, some highs, some lows and some in-betweens.
"It’s definitely taken some adjusting but I’m just me, a girl from London loving her football and that’s what I’ll always be. Hopefully we can have many good moments together with England."
Despite being in a clique, Kelly insists that the England squad is full of "good people" who are supportive of each other.
She said: "We’re good people that support each other every day.
"We support each other very well as a 23, that’s what it takes to win a tournament. In football sometimes cliques are negative, but this is a positive clique."
Kelly added: "We have such quality in our team which is great for us. Not only in the games but in the training sessions we’re pushing each other, too. It’s healthy competition. You have to be at your best here and that’s really important."
