Best approach to an app

hi im building an app that will be used within multiple different companies to store non-sensitive informations such as timings. would the best approach be to create a seperate database for each company or to do it via different collections inside of one database.

Honestly, personally, I would just use one database/collection and give each record permissions such that only users with a certain label can access that record. Then when onboarding users for different companies assign users a label for x company.
