Google Sheets AppScript for Team Permissions

I'm seeking a Google Sheets join team , we create Gsheets and appscripts for clients. We have 1 dev but they have limited skills in google projects security. I am unable to test the scripts even though my account is the owner of the drive. If you have good googel permissions skills here please join teh team and help resolve and work on projects going fwd. When we roll out to clients we need to ensure they can use the sheets+scripts
(that access a google drive folder with edit rights) so the go live is smooth.

Ideal skills for this job include:
- Experience managing permissions within Google Appscripts
- Proficient in Google Sheets and AppScript
