Any experience using LinkedIn, either posts or ads, as a marketing channel?

A key use-case for my latest startup JustToSay Cards is farewell cards for hybrid/remote teams and I figured that organising those often falls to office managers, team leaders and others in those kind of roles, so I wondered if LinkedIn, ads in particular, which seem to provide pretty granular targeting) might be a way to reach them.

Does anyone have any experience they could share? Is it worth it? What kind of content / ads work best? What kind of cost / results could I expect?

Thanks in advance!
