The club has a special place in Mariam's heart, she says.
Jenny Sugarman took the helm at the club in the summer of 2021.
The 18-year-old is quickly becoming a fans' favourite at the club and recently featured in West Brom's kit launch.
There is still more to come from her.
In her first interview with Sky Sports News, she said it felt like she'd been here a long time.
I have been here since I was in the U14s and there is no regrets. It was the first academy side that I was a part of.
The club is in my heart. I am in the first team because I have grown as a person and a player.
I want to score more goals. I want to get fit, sharper, and improve my decision-making, but I think that will happen as I get older.
Mahmood scored in a behind-closed-doors friendly against Derby County earlier this week to get her pre-season back on track.
The first women's game ever to be staged at The Hawthorns was the 2-0 win against Derby last season.
"That made me feel good," he said.
The opportunity to play at The Hawthorns was an amazing experience. It was pleasant. We want to do it again.
South Asian heritage footballer Kira Rai, who plays for Derby, is a friend of Mahmood's.
She hopes that when other girls see us play it they will see that they can be who they want to be.
It means a lot to me. Hopefully, some of them will one day get a chance to play in an amazing football stadium like we did, because I want to inspire youngsters to come and play the game.
At the Women's Euros, the glaring lack of ethnic diversity at the elite end of the women's game has been brought into focus, with England fielding an all-white starting XI in all three of their group games.
Sky Sports recognised and began taking steps to address the lack of diversity in the women's game back in 2020 as part of its commitment to tackle systemic racism.
Sky Sports has worked with dozens of current and former players from different ethnic groups to try and inspire the next generation of female football players.
As part of Sky Sports' commitment to British South Asians in Football, talent has been identified and signposted directly to the Football Association and clubs, as well as creating a section on our website to raise awareness about South Asians in The Game.
A number of elite and potential female players and their families have been supported with off-field opportunities.
The 'Seeing Is Believing' event for the century-old west London sports club Indian Gymkhana was one of the ways Sky Sports supported participation across the country.
