Choose the least access that still supports the task: no library access, selected photos only, or broader access when iOS offers it. Camera permission is separate from permission to browse the existing photo library.
2
Open the Photos privacy list
Open Settings > Privacy & Security > Photos. This list contains apps that have already requested photo-library access; an app may not appear until you try to select or upload a photo inside it.
3
Select the intended app
Tap the app name and review the currently allowed level. Confirm you selected the correct app, especially when related apps from the same company are installed.
4
Choose the new access level
Select the access level iOS offers for that app. With selected-photo access, choose only the items needed and use the edit-selection control later when the app should see a different set.
5
Test the feature and review later
Return to the app and retry the upload, attachment, or editing action. If it works, leave the narrower permission in place; revisit Privacy & Security whenever the app no longer needs access.
If the app is absent, open its photo picker once so it can request permission. If no prompt appears, check Screen Time or device-management restrictions before reinstalling. Changing access does not retract photos already uploaded or sent; manage those in the destination service.
