Cannot install via Plugin Store under Craft 3.4.18

[watershed]

After reading this thread, which led me to NYStudio107's #1 solution to robust queue handling, this plugin sounds like it could help with my slow Feed Me import :)

But when I go to install it via Craft 3.4.18's Plugin Store I get a verbose error message, the top portion of which is:

Composer output: Package "craftcms/vue-asset" listed for update is not installed. Ignoring.
Package "danielstjules/stringy" listed for update is not installed. Ignoring.
Loading composer repositories with package information
Updating dependencies
Your requirements could not be resolved to an installable set of packages.

Problem 1
- symfony/process v4.2.0 requires php ^7.1.3 -> your PHP version (7.2.29) overridden by "config.platform.php" version (7.0) does not satisfy that requirement.

There then follows a string of similar but not identical symfony/process messages, and then:

- Installation request for ostark/craft-async-queue 2.1.1 -> satisfiable by ostark/craft-async-queue[2.1.1].

Running update with --no-dev does not mean require-dev is ignored, it just means the packages will not be installed. If dev requirements are blocking the update you have to resolve those problems.

Hi

Your composer.json pins the php version to 7.0, but some dependencies of this plugin require at least 7.1.
Fix
composer config platform --unset
composer update

And try to install the plugin again.
