@soatok Well, both of my previous relationships were in my 20's but maybe as a demi ace, my experience could offer insight

The first was a guy from a local furry group who I was already talking to and was pretty open with (I was even more introverted back then) and after inviting me over for a night to hang out, we hit it off and had a good few months

The second was a lady I knew from work (she quit by then) who I knew was really into games (specifically Zelda) and I invited her out to the Zelda Symphonic Orchestra. She invited me over later, she kissed me at her home, and I asked her out right then. That relationship went better

In both cases, it was through general like interests that, when presented the opportunity for an intimate 1 on 1 event (not strictly for dating reasons), we found our wavelengths were compatible, and allowing for romance led to both becoming real romantic relationships. Granted, these were both in person so I'm not sure if it would work remotely, but any meetup might be a start
