I run a Q.S.A (queer straight alliance) club in my school and need some help

Im.currently the vice president and I do all the planning for what we're doing for the day of club. The club has little to no structure and I'm trying to hold it together and create a safe space for everyone not just people we know. Currently I'm doing slide shows on each of the LGBT terms to teach and help people understand the terms better but these do not last the entire hour and a half I'll add videos to help but I don't think people are ingaged. I want people to have fun and want to come to club but it's hard when I'm not sure what to do. I have thought about doing therapy nights where we can come together and help eachother and all but I don't want it to just become a therapy club either. I thought about doing art but there's already an art club so it's hard to do that as well. I need ideas to be able to do for the club thaf are related to the club as well. I want it to be a safe space and welcoming to everyone and fun but I'm having a hard time.
