Is it okay for me to join a dating app for lesbians if I'm bi/pan but looking for a girlfriend?

Hello all!! I know I'm probably overthinking this but I thought I would ask. Technically I am bisexual/pansexual (Still trying to decide between these 2 terms honestly) and not lesbian which seems to be the target group for this dating app I want to download and I don't know if it would not be right or okay for me to do so. I know I'm probably overthinking it but thought I would ask anyway. If it has any bearings on it, I haven't had a girlfriend yet but I do know I'm attracted to girls as well as guys. Sorry if it seems confusing, I'm writing this on a phone so can't proof read very well
