Can i play story missions with my custom character in gta online?

The excerpt from Wikipedia describes GTA Online as an online multiplayer component of Grand Theft Auto V, mentioning its open world and player customization. It does not address the availability of story missions or whether they are restricted to certain characters. Because the evidence does not provide details on story mission access, we cannot confirm or deny that a custom character can participate in them. To obtain a definitive answer, consult official Rockstar Games documentation, community guides, or support resources that cover mission prerequisites in GTA Online.
