Other than music videos and such, I think his only true acting credit was a cameo on “The 100” years back, where his role was just a set up to play piano and sing during a montage. He also did bit parts in an SNL skit or two.
I have no doubt he’s been offered roles, but I suspect he’s usually been offered fluff YA romance type roles (we know he was up for Love, Simon)... he has the looks certainly, but his voice betrays him and is too soft for the roles he probably would want (and maybe he’s been a bit discouraged if all he keeps getting are scripts for gay/queer roles).
