Dynamics 365 Business Central Team Members users can do the following:
• Read anything within Dynamics 365 Business Central
• Update existing data and entries in Dynamics 365 Business Central - existing data are records like
customer, vendor or item records which are already created. Entries means entries on which it is specifically allowed from an accounting perspective to update specific information. (e.g. due date on customer ledger entries)
• Approve or reject tasks in all workflows assigned to a user
• Create, edit, delete a quote
• Create, edit, delete personal information
• Enter a time sheet for Jobs
• Use PowerApps for Dynamics 365
SO: the answer to your question is No, you cannot do that with a Team Member license.
If you use PowerApps, this could be ok.
An external user could be the best choice for on-prem solution with web services.
