Looking to fly with just a couple old guys like me

I’m a silver surfer in the UK. Used Flisims since way back., all kinds of planes an ‘copters. Progressed to MSFS2020 in last year or two. Multiplayed in previous ‘FSX’ Flisim and do so now in MS20 with several buddies in formation, with headset comms on Discord. Baffled as to how difficult it is to find new friends on this platform, both in MS20 and in Discord itself. I was invited by a.n.other and haven’t been able to understand how to invite others myself! I often dogfight Spitfires (‘Spit’ on nameplates) with other random pilots around EGSU Duxford and EGLC London City , UK. My aircraft nameplate shows as ’ joedoh119’ in the game while my Discord handle is joedoh11945#8380. Not being highly tech, I hope someone comes up with an answer after 2 years on.
