You shouldn't share one single company account across the team. Everybody should have their own account, of course on the company domain, and use that one.
Advantages
1. You know who does what.
2. If Google bans an account the others keep working.
3. Permissions per employee, because not everyone need to to everything.
4. If an account is compromised, you ban the account.
5. When an employee leaves, you ban the account instead of changing the password.
6. N people sharing a common password on an account nobody has particular responsibility for, ouch.

No one said anything about using a single account.
> Everybody should have their own account
This is moot if your company uses GSuite. The concern is that if a GSuite account is linked to a GCP account, and suspicious activity happens on Google Apps that it can result in interruption to GCP (and vice versa).
