If you are added to a Sales Team with read/write access you then have the ability to extend sharing on the opportunity to other users.
If you are added to a Sales Team with read/write access you then have the ability to extend sharing on the opportunity to other users.
If you are added to a Sales Team with read/write access, you do not inherently have the ability to extend sharing on the opportunity to other users. Typically, in Salesforce, only the record owner or someone with full access permissions has the ability to share records with other users. Therefore, being granted read/write access is not sufficient to extend sharing; additional permissions are required.
I think only record owner can share with others.
If your Salesforce admin has enabled opportunity teams, the Opportunity Team related list appears on each opportunity. You can add, edit, or remove team members.
Opportunity Teams can grant record access to the users who are supposed to collaborate for closing it. The different options are available depending on the organization’s sharing settings. https://www.salesforceben.com/salesforce-opportunity-teams/
Why the reveal resolution is showing as False?
Went to check in Salesforce.help and it says "Further, only users who own Opportunity records can add/remove opportunity team members. Users with read/write access to the Opportunity should also be able to do this"
